In Frederick Co. VA there are deed records that show, as either witness or owner of adjoining land between 1755 and 1774, individuals named "Adolph Ilor" and "Jonas Rhinehart" and in Dunmore Co. VA similar records involving "George Rindhart" and his assignor "Mark Ilor" between 1761 and 1774 [Northern Neck Land Grants, p.307]. During both of these periods Adolphus Jonas Iler was born, possibly named for siblings and/or parents of his parents.
Frederick Co. VA was formed in 1738 from Orange Co. (see present day map for location of Frederick Co. It is the northernmost county in VA, bordering WV not far from the state of Maryland. Dunmore Co. VA was formed on May 15, 1772 but renamed Shenandoah Co. on Feb 1, 1778 and now borders Frederick Co. to the southwest (see present day map) [familysearch.org, "Virginia County Creation Dates... "].
In 1768 Marcus bought land in what became Bourbon Co. KY from Isaac Ruddle. In 1773 "Marcus Isler" sold land to Adam Halker in what was Dunmore Co. VA and became Shenandoah Co. VA in 1778. According to Dunmore Co. Court Minutes dated Aug 27, 1776 "Mark Iler and wife" transfered land to Henry Fravell [McBee, p. 596].
Between 1773 and 1778 the "guard ship" Royal Oak was stationed at Portsmouth (VA). On Dec 13, 1778 it sailed to the West Indies [threedecks.org, website]. Joseph Ford Sr., 1724?-1804, said that Mark came with him to [West Florida] from England on the ship Royal Oak about 1774 [McBee, Book B, p. 247].
Father Marcus seems to have arrived in Natchez about 1775 when it was part of the Province of British West Florida, but left when the Spanish took control and claimed land in the Cumberland Settlement of Washington Co. NC [now Tennessee] because he was a single taxable there in 1787 and a "Melchior Fain", also known as Marcus Fain, assigned his 640 acres on the Little Harpeth River as a Private in the Continental Army to Thomas Malloy, issued in 1797, but there is no entry date in the record [NC Land Records website].

In May 1782, "Xphal Ryer & wife" arrived at Natchez without children or slaves. The "wife" may be the "Eliza Ophill" in the St. Catherine's Creek area in one of the translations of the 1792 Natchez District Census, identified as a widow (in Spanish) of Iler [similar in sound to Ryer). The only other "familia" to arrive that day without children was recorded as William Barland under the name "Guillermo Barland" [Natchez Court Records, 1767-1805, record at the Archives General of the Indies, Spain]. A total of 13 families were recorded by Spanish authorities as arriving, and the record was signed by Commandant Charles de Grand-Pré on Jul 6, 1782.

About 1785, Jonas married Martha Ann who was older than 45 in 1820. On Jan 17, 1835, as the adminstrix of Jonas Iler, she advertised that she was to sell Jonas' slave George at the courthouse on Feb 24 [Woodville Republican, Jan 17, 1835, ancestry.com website].

On Jan 18, 1787 a Census of the Natchez District was reported to the commandant, Charles de Grand-Pré:
There were 1,926 Individuals; 25 male births, 20 female births, 4 male deaths, 3 female deaths, and 356 were able to carry arms.
In Saint Catherine [St. Catherine's Creek section] 10 individuals were counted in the family of "Mark Oiler":
3 white males in age group 1 [Mark, Jonas, William Barland];
1 white male in age group 2 [Andrew Barland];
2 white females in age group 1 [Elizabeth, aged 21, and Anne Marie aged about 40, the wife of Jonas];
1 white female in age group 2 [?dtr of Jonas' wife nee Miller];
2 male mulatoes in age group 1 [slaves];
1 female mulatoe in age group 1 [slave];
and 12 cattle; 3 horses, 30 hogs [Baker, wiki website].
In 1787, a George Fourney sold to Marcus Tyler [Iler], "140 arpents he purchased from John Row, near the Fort, bordered by lands of John Hartley, John Lusk and Saint Germain, for $400, $200 at end of present year [1787]; $100 at end of 1788; $100 at end of 1789" [McBee, Book A, p. 64]. This may be where Iler had begun building Hope Farm, which was eventually bought by Natchez District Commandant Charles de Grand-Pré to be his residence.
On Jun 25, 1787, stepbrother Christopher Miller and possibly Jonas' mother, Anne Marie Miller, all witnessed the will of Lucy Crane. The witnesses were recorded by the Natchez Court on Aug 26, 1787, upon notice of her death, as "Moore Cilon, Jonas Cilon, Christopher Miller, Esther Bradshaw" [McBee, p. 42]. "Moore" may have been misread or transcribed from Mark or Marie, and Cilon the same from Oiler, meaning the Crane will was witnessed by Mark Iler and Mark's eldest son and eldest stepson.
On Nov 3, 1788 "Margaret Tyler" (likely wife Martha Ann Iler) was one of the witnesses of the will of Anne Gaillard [McBee, Book B, p. 59].
On Dec 31, 1788 a William Miller family of 3 (possibly with his second wife and a child), along with two other families ("Fooy" or Foye and Bassitt), arrived in Natchez from the "Chacta (CHOCTAW NATION)" which meant they travelled by land either from the east, possibly through Alabama and from as far as the Carolinas, or down the Wilderness Trail which became known as the Natchez Trace [MDAH, website].
On Mar 19, 1789, "Having received notice from Jonas Hailer of the death of his father, Marcus Hailer, commandant [Grand-Pré] and others repaired to his plantation, 1 mile from Fort, to take an inventory of the deceased Marcus Hailer who died interstate [without a will], whereupon Jonas Hailer was interrogated and he made the declaration that his father had no children but the deponent and that he left no wife" [McBee, Book B, pp. 247-8].
Historians of the Hope Farm off of Homochitto Street in Natchez believe the back part was built by Mark Iler about the time he arrived there in 1774-5 "while the city was under British rule; the front wing was added by Carlos de Grand-Pré" [Historic Houses of America, American Heritage Books, 1971], after he purchased it from Jonas on Mar 21, 1789 for $100 a "parcel of land formerly belonging to John Row and afterwards to John Forney from whom my deceased father Marcus Hailer, purchased" [McBee, Book B, pp. 247, 581].
In a 1789 deposition after the death of Mark Iler was reported by his son, Jonas, "Joseph Fort" (Joseph Ford Sr., 1724?-1804) said that Mark came to this country from England on the ship Royal Oak with him about 14 years ago [1775] and "he did not know him to be married nor that he had other children than the one present [Jonas] whose mother died in America" [McBee, Natchez Court Records, Book B, p. 64]. Six "young men" came to West Florida in 1775 from England aboard the ship Royal Oak, participated in the West Florida rebellion in Bayou Sara (before it was part of the Natchez Dist. and now within Louisiana), and then settled in the Natchez District [Louisiana Anthology, website].
Bayou Sara no longer exists because the Mississippi River now runs through it. In 1820 it was partly in Wilkinson Co. MS (formed in 1802 from a part of Adams Co.) and a part of West Feliciana LA, south of the town of Natchez (see present day map for location of Wilkinson Co. and present day map for location of West Feliciana Parish.
A Spanish grant to "Mark Oiler" for 400 acres on St. Catherine's Creek, 5 mi. east from Fort, bordered by lands of Mr. Andrews and Richard Adams, Lewis Bingaman and Peter Surget (also in the 1792 Natchez Census) was mentioned later as the 400 acres bordering lands of "Mrs. McIntosh" and others, that was "sold by his lawful heir to Christian Harman [McBee, p. 384].
In 1789, "Jonas Oiler" sold 100 acres "adj. Adam Bingaman and Mrs. McIntosh", to "Wm. Groding" for $200 [McBee, p. 460]. The land was about 3 miles east of Natchez. William was likely a son of Richard Goodwin who had died by 1786.
The Will and Testament of William Barland, Adams Co., MS, written Jun 19, 1806, proven in Apr 1816. In it he states that on Apr 7, 1789 he "did purchase my friend and companion Elizabeth Barland and three infant children, ... of Jonas Eiler, then of the City of Natchez, of whom the said Jonas Eiler then put me in possession, and furnished me with a legal Bill of Sale..." [Historic Natchez Foundation, Miss. St. Univ., website].
On May 17, 1790, "Jonas Eiler" sold to William Barland "a mulatto woman 'Elizabeth', aged 25, nat. of America, with her four children, for $700 specie, paid" [McBee, p. 78]. If she was the woman identified by the Spanish as the "wife" of Marcus in May 1782, she would have been about 17 years old then.
According to a translation of the 1792 Spanish Census for the Natchez District, there is no Barland household, but there is an "Oiler, the Gentleman" household with 8 white members, and one black, living on 800 arpents of land. This would have to be William Barland, Elizabeth, their five children, and Jonas Iler, the heir of the estate. The translator may have confused "Gentleman" for the Spanish word for widow [Adams Co. Gen. Hist. Network].
About 1804, son Abram married a woman possibly named Pherby or Phereby or Pheriby. Their daughter had the same name, was born in SC about 1805 and lived in Wilkinson Co. MS in 1850 with a daughter aged 13 born in MS [Sheet 301A, Household 535]. In 1836, after son Abram had died, the administrators "William and Pherby Iler advertised that fourteen slaves were to be sold with furniture and land 4 miles west of Woodville ... by Percy's Creek" [Woodville Republican, Dec 3, 1836, ancestry.com website]. Abram's son William was born in 1811, lived in Wilkinson Co. in 1840 but later moved to Caddo Parish LA where he died Nov 22, 1882 and was buried in Shreveport LA. Pheriby died after 1850.
On Sep 7, 1805, a signed agreement between "Abraham Iler" and the sons of "Mark Iler" was submitted to the Adams Co. Court. A transcription of the agreement which was signed by Abraham Iler, "Jacob Eiler", and "Job Routh". The "believed" death of Jonas is mentioned. The Ilers' eldest stepbrother, Christopher Miller, also signed the agreement on the same day "to lend myself as surety that the above named Jacob Iler shall comply" [Adams Co. Chancery Court file, "Estate of Mark Iler (or Eiler) deceased", box no. 49, item 4].
On Sep 26, 1805, an inventory was authorized for the estate of "Jonas Iler, late of said county [Adams] deceased" [Adams Co. Miss. Terr. Orphan's Court].
The Will and Testament of William Barland, Adams Co., MS, written Jun 19, 1806, proven in Apr 1816. In it he states that on Apr 7, 1789 he "did purchase my friend and companion Elizabeth Barland and her four children of Jonas Eiler, then of the City of Natchez, of whom the said Jonas Eiler then put me in possession, and furnished me with a legal Bill of Sale..." [Historic Natchez Foundation, Miss. St. Univ., website]
On Nov 3, 1806, Monday evening, Jonas' mother died in Natchez in the "59th year of her age" [Mississippi Messenger of Natchez, obituary of Mrs. Anne M. Eiler, Tuesday Nov 4, 1806].
In the Will and Testament of William Barland, Adams Co., MS, written Jun 19, 1806, proven in Apr, 1816. In it he states that "on or about" Dec 27, 1792 his house was burned, losing Jonas' bill of sale and manuscription from 1789 in the fire. On Jun 6, 1797 he "did confirm the freedom or manuscription" [Historic Natchez Foundation, Miss. St. Univ., website].
In the 1816 Adams Co. MS Census, page 19 (line 21), there was the household of "Eliza Barland" with:
4 males under 20 [Jonas' sons William and Abram, her sons Andrew & James Barland],
1 female over 20 [Elizabeth Iler],
2 females under 20 [her daughters Nancy, Susannah],
and 15 slaves On page 21 of the same census on line 10 was the household of "Jacob Eiler" with 2 males older than 21 [Jacob, ?his brother Abram],
one male under age 21 [his brother Thomas],
and no females or slaves [MDAH, Adams Co. Census].
On Oct 17, 1816 son Jacob married Eleanor Martha Smith (1798-1851) at St. Francisville, West Feliciana Parish LA. Her tombstone at the Routh Cemetery across from Dunleith Plantation in Natchez reads "Wife Of Jacob Eiler Born 6 Jan. 1797 Died 5 Jan. 1851 Aged 54 Years... Her Remains Here Deposited Near Her Husband's Father & Mother".
St. Francisville is a city along the northwest bank of the Mississippi River. See present day map for location in West Feliciana Parish. Wilkinson Co. was formed in 1802 from a part of Adams Co. and a part of West Feliciana Parish, south of the town of Natchez (see present day map for location of Wilkinson Co.)
In 1820, son "Abram Iler" headed a large household of 27 members in Wilkinson Co. MS. On page 364, line 20 of 1820 Wilkinson Co. Census the oldest white males in the household were aged 26-35 [born by 1795], and four were counted. There was one white female aged 45 or older [born by 1775] and one female aged 26-35. 8 members, including 4 slaves, in the household were engaged in agriculture [USGenWeb, website].
Son Abram was a butcher. He placed a notice on Oct 13, 1827 that "he was no longer butchering [Woodville Republican, Dec 3, 1836].
Son Thomas executed a deed of trust dated Jan 17, 1837 to secure "William Iler and Phereby Iler, the administraters of Abraham Iler" to settle payment of a promissory note [Woodville Republican, Mar 18, 1843].
Son William was a blacksmith in 1839. On Oct 13 of that year he advertised that "he had opened his new shop after the fire" in Woodville on the street that "ran past the jail and the Baptist church, next to his wagon shop" and other businesses [Woodville Republican, Oct 18, 1839]. He was renting a space to a cutlery and gunsmith shop in Jan 1842, and a William T. Iler and a "William Iler, Junior" were "wagon makers and coach repairers" in 1841 [Woodville Republican, Mar 18, 1843].
In the 1850 Adams Co. MS Census, enumerated on Jul 26, 1850 in Household 206 on image 33, "Jacob Eiler" aged 63, merchant, had Eleanor M. Eiler, aged 52, born in LA, and Ellen Eiler aged 11. His land was valued at $7,500 [U.S. 1850 Adams Co. MS Census, familysearch.org website].
In 1853, "Jacob Eiler" was listed on page 9, on line 18 of the first column, as head of a household of 1 free white male and 2 free white females in Adams Co. outside of the city of Natchez [MDAH, Adams Co. MS 1853 Census, page 9, col. 1, line 18].

The will of Jacob Eiler, dated Mar 15, 1855, probated Sep 1869, mentioned nieces through half-brother Joash Miller, deceased, and of Christopher Miller [Adams Co. Will Book 3, page 371, find-a-grave website].
