I have been doing some research on my Rogers line in Montgomery Co, VA during the Revolution and came across a couple of references to Henry Trolinger that I thought you would find of interest:
-"The Patriots at Kings Mountain" by Bobby Gilmer Moss, p.250: "b. 10 Mar 1762/2 Mar 1763, Orange Co, NC d. 28 Feb 1844, m. Mary Thomas __ Mar 1789, Orange Co, NC Henry was the son of Henry Jacob and Barbara Trolinger, stated that he was of German parentage and that his name was pronounced "Drollinger".Trolinger moved with his father to Montgomery Co, VA, where he was engaged under his father in manufacturing gun powder until summer of 1779.At that time, he was drafteed in the militia under Capt. Abraham Trigg and Col Campbell.He enlisted during Apr 1780 under Capt. George Parris and a little later enlisted under Capt. Trigg and was in the battle at Kings Mountain.Trolinger was allowed pension on his application executed 14 Sep 1832 while residing in Orange Co, NC.His widow, the daughter of Griffith Thomas, was born 25 May 1770.She was granted pension on her application executed 20 Aug 1847 while residing in Orange Co.FPA W4087.
It appears that Henry was in fact not at the Battle of Kings Mountain, but was instead at the Battle of Shallow Ford that took place a few days later.See "William Preston and the Allegheny Patriots" by Patricia Givens Johnson, p.265.Note that many of the men that took part in the Battle of Shallow Ford were reportedly at Kings Mountain.They were headed that way, but arrived after the battle was over and were diverted.
Let me know if you run across any thing on the Rogers of Cripple Creek, Montgomery (now Wythe) Co, VA.They too were in the powder making business.
