Thank you for your excellent information on this family.As you noted, a lot has been written apparently without looking at the will and estate records for John Adams (1775-1854).Consequently, there has been much incorrect speculation in identifying his children.
I wonder if you have also researched the ancestry of John Adams (1775-1854) of Marion County, IL?I have "known" of him for many years due to the 9 Feb 1796 marriage bond in Pittsylvania County, VA for John Adams and his wife Nancy Burton.The will of Nathan Adams, Sr. of Pittsylvania County, Va (a son of William Adams d. 1769 Charlotte County, VA) was written 28 Oct 1801 in Pittsylvania County, VA and presented there for probate on 20 Sept 1802.In it, Nathan Adams, Sr. named8 children including his son John Adams who received 50 acres where Nathan was living, a daughter "Polly Adams," and a son Nathan Adams (Jr.).
John Adams, the son of Nathan Adams (d. 1802), appears to me most likely to be John Adams (1775-1854) last of Marion County, Ill.One of the reasons why is that the "Polly Adams" named as a daughter of Nathan Adams, Sr. (d. 1802) also may have settled in Marion County, IL -- at least from records that I was sent by a Dr. W. "Bill" Farthing Sargent in 1984. To follow is what he sent me.I have not verified these records and offer them now only as clues for further research:
Dr. Sargent noted that "Polly Adams," daughter of Nathan Adams (d. 1802), first married (bond dated) 17 Dec 1803 in Pittsylvania Co., VA to Dudley Farthing, son of Richard Farthing & Grizzel Watson. She was listed on the marriage bond as a daughter of Nathan Adams "who consents," though that may refer to her brother Nathan Adams, Jr. "consenting."Surety for the bond was John Adams (her brother?) (Note: "Polly is often a nickname for Mary).
According to Dr. Sargent, Dudley Farthing and "Polly" (Adams) Farthing moved in the early 1800s to Logan County, KY where Dudley died ca. 1824.They had children including a daughter Emily Farthing who later married 2 Jan 1834 in Marion County, IL to John Robert Wooters.Before that, Emily's mother, "Polly" (Adams) Farthing appears to have remarried to a Mr. McGee/Megee probably either in Logan County, KY or in Robertson County, TNwhere she also seems to have lived for a while in the later 1820s.By the early 1830s, "Polly" seems to have been widowed a 2nd time, and had moved to Marion County, IL.Reportedly, "Polly"/Mary (Adams) Farthing McGee/Megee died about 1854 in Marion Co., IL where she lived with her daughter Emily (Farthing) Wooters and her husband John Robert Wooters.(Note:Another son of "Polly" was Hamilton Farthing who married 9 July 1833 in Marion County, IL to Elizabeth Wooters, noted to be a sister to John Robert Wooters, with both being children of Leven Wooters.)
So why did "Polly" move to Marion County, IL?Perhaps she migrated there with her family at the time that John Adams (1775-1854) came?Indeed, you reported that this John Adams previously lived in Logan County, KY -- and, as noted, "Polly" also lived there.
Now, to add more circumstantial evidence (again, this needs verification, since I was only sent this information and did not personally research it):Nathan Adams, Jr.(son of Nathan Adams d. 1802) married (bond dated) 16 Feb 1809 in Pittsylvania County, VA to Sally Murphey.They moved to Clark County, KY before settling in Robertson County, TN where he died in 1839.His estate record listed a 2nd wife and several children, with one of his sons being Lewis V. Adams.
The 1860 & 1870 census of Marion County, IL reported a Lewis V. Adams b. c1815-17 in Tenn. as living there with his family.Is this the same person as the son of Nathan Adams, Jr. (d. 1839)?If so, then we seem to have a nephew to John Adams (1775-1854) and Polly/Mary (Adams) Farthing McGee/Megee (d. ca. 1854) also living in Marion County, IL.
With your fine research in Marion County, IL, maybe you (or others) can verify or refute some of this information and can post additional findings on this Forum.It may well be that even more descendants of the large Adams family of Pittsylvania County, VA ended up in Marion Co., IL via some of the same Kentucky or Tennessee counties connected with John Adams (1775-1854) and Polly/Mary (Adams) Farthing McGee/Megee (d. ca. 1854).
If you have information on the ancestry of John Adams (1775-1854) of Marion County, IL, I'd be most interested to learn about it.
One final comment:I descend from both John Adams (d. 1815) and Robert Adams (d. 1783) whose wills were recorded in Pittsylvania County, VA.They appear to be brothers of Nathan Adams (d. 1802).Neither is the father of John Adams (1775-1854) of Marion County, IL.John Adams, Sr. (d. 1815) had a son John Adams, Jr. (d. 1824) who remained in Pittsylvania County, VA.Robert Adams (d. 1783) did not have a son named John Adams.
