My Family Tree

Possible brother of John Chambers - a "Tho's Chambers" appears alongside John Chambers as sargeant in Colonel John Gibson's 13th Virginia Regiment. Muster roll of 8 June 1777 at Fort Pitt lists him [part illegible...Apr 20 1778?]. Also appears in Col John Gibson's list of those who served under him 1780, 4 lines after John Chambers. "Thomas Chambers, Sergeant, discharged October 14, 1780. He probably died before 1818 since no Rev. War Pension application exists for him. [Note that John named a son Thomas in 1789]

In the 1807 Indiana State Tax List, Knox County, appears a John Chambers, Thomas Chambers, Sr, and Thomas Chambers. Altho some claim a Thomas Chambers son of Alexander Chambers, who died in Knox Co, IN 1834, he does not show up till 1810 US Census. Likely that Thomas, Sr is John's brother.

Another "Alexander Chambers" on the list of men in the "13th Virginia Regiment" at Ft Pitt who volunteered for the expedition to New Orleans Dec 22nd 1777 (Fold3) This was "Willing's Depredation" https://en.wikipedia.org/wiki/James_Willing. Curiously, Alexander Chambers is not listed in the company January 1778. http://freepages.history.rootsweb.com/~haefner/Rattletrap/1778_Jan%20Capt_Willing_Rattletrap.pdf This is not the Alexander Chambers (1752 Ireland - 1834 Knox Co, IN ) of pension S32173.
Excellent account of the 1st Marines: http://freepages.rootsweb.com/~haefner/history/Rattletrap/
A short statement found in VA Land Bounty Records (rev war pension VAS2947) says "Discharge signed by Lt Col Richard Campbell...'Please take out my Land Warrent from this discharge 3rd June 18?? Alex Chambers'". Lt Col Richard Campbell from Fincastle fought together with Capt John Gibson's 13th regiment Dec 12 1776.
Alexander Chambers first enlisted July 18th 1777 remark: "at the S.P. Hospital". http://revwarapps.org/b135.pdf from the Muster Roll of Capt James O'Hara Independent Company of Regulars's at Fort Pitt Oct 1st 1777. ==> John Chambers says he was also discharged at Fort Pitt by Lt Col Richard Campbell.
So this Alexander Chambers appears in the Indiana DAR roster, b.1756 Rockbridge Co, VA d.1857 Jefferson Co, IN, m. Rachel Monroe. Son of David Chambers and Sarah Sloan of NJ. No connection to John Chambers of Hampshire Co, VA.

A third possible relation is James Chambers who was hung for desertion from Fort Pitt about 14th May 1778, pg49:
