Lee, I can say for sure I know of two John Wallaces from York. One was a son of Oliver Wallace Sr. who came from PA to Mecklenburg Co.- turned into Tryon in turn turned into Camden and then the York most people know of. Olivers son John though left around 1800 and joined his Father and others in Oglethorpe/Clarke Co.'s GA. So that is one less. I will look at the references to the John in Military and rewrite you. I do not know if he was yours but as you say your John died in 1816 it puts him into this frame. I can also look at my notes again and it may be that James L. also a son of Oliver Sr. I think also had a son so named. It seems that these people were coming and going all the time. We have seen from information, correspondances and notes that people were moving frequently so it looks hard but not impossible to research. C.M.
