I've traced one of my lines back to the Dobsons of western Pa., ending with a gggggg grandfather, George Dobson Sr. of Bedford County. He died in 1764, shot & scalped by American Indians outside Fort Bedford (Helm, David A., "Helms of Germany & Pennsylvania"). One of his sons, George Dobson Jr., later moved to Butler County (& is mentioned earlier in this thread).
I apparently descend from George Sr.'s daughter Lilly Ann Dobson, who m. George Lucas Sr., an Irish immigrant who farmed in Bedford County, fought in the Revolution, got charged with treason during the Whiskey Rebellion, & died in Johnstown, Cambria County in his 90s.
Anyway, wondering if anyone is familiar with this line, esp. George Dobson Sr. & his origins or George Lucas Sr. & his. George Dobson Sr. was a farmer & an early settler in Bedford County, starting a farm there sometime before the French & Indian War. The earliest mention of his death that I've seen comes from "Papers of Henry Bouquet," vol. 6, pp. 503-504. I have no idea where he came from, although the family seems to have had some ties to Virginia (George Dobson Jr. fought in the Revolution, & one of his enlistments was from Staunton, Augusta County, Va.).
