Regarding Sylvester Chunn Documentation: This may be "old hat" for serious Chunn researchers but I have the following docs on Sylvester Chunn: (1) Rev War pension records (2) Rev War Federal Compiled Service Records, and (3) several References to Sylvester in the James Norman Smith Memoirs (James Norman Smith vouched for Sylvester when he applied for a Federal pension for his Am Rev War service.)
I am not a Chunn - I'm a Smith. My 4-great grandfather James Smith and Sylvester Chunn were life-long friends. Apparently Sylvester's parents and James' parents were also close. In any event, Sylvester was so close to "my" Smiths that that Sylvester was considered a family member. He was refered to as "Uncle Syl" and was included in at least one Smith will.
According to the James Norman Smith Memoirs, Sylvester and James served in the Am Rev War together. (FYI - James Norman was the son of James, friend of Sylvester) Smiths being almost impossible to sort out, I searched for Sylvester Chunn's Rev War military record instead and, bingo!, there was my James Smith enlisting on the same day and serving along side of Sylvester for three years...they were at Valley Forge with Washington as well as at the battles of Brandywine, Germantown, and Monmouth.
James and Sylvester enlisted in a Virginia Regiment "on Continental Establishment" in early in 1777 (January). Thus, the two friends were "Continental Soldiers" - not Militia. The records show Sylvester's rank at enlistment as "Fife". After about a year his rank changed to Private and remained so till the end of his enlistment. The records show that he was honorably discharged in late 1779 - early 1780. My James Smith stayed with the regiment as James had previously extended his enlistment to "Duration" (of war). Sylvester, dischaged, appears to have returned to their home in Halifax County, VA while James went with the regiment to the Siege of Charleston. (We lost that one big time - an entire Continental Army was taken captive by the British.) In any event and if the James Norman Smith Memoris are accurate, a year later in March of 1781 the two friends found themselves on yet another Revolutionary War Battlefield - Guilford Courthouse - as members of James Smith's uncle, Captain James Turner's, Halifax County, VA, "Minuteman" Militia. It was there that Sylvester's friend James receives a musket ball that shattered his thigh and crippled him for life.
After the Revolution, Sylvester remained a part of the (Smith) family moving with them and living near them till his death.
So, in memory of the life-long freindship of Sylvester and my "many-great-grandpa" James, I'd be happy to help share what I have on Sylvester Chunn with any of his descendants.
