Ihave spent some time on Allens and believe John Spurlock in ca 1791-94 Elbert Co., Ga. was from Surry County. N.Car. I think his wife was Sarah Alle, both born ca 1722 in Henrico County, Va.
The Allen who was killed by Indians inca 1790 Georgia was their son.
Allen of ca 1810 Oglethorpe County, Ga who married Frances Traylor and went to Ms. was the son of the slain Allen. Robert who also went from NC to Ga to Ms was this younger Allen's uncle.
The David who paid for land for John Spurlock's children (or grandchildren ?) in ca 1794 Elbert/Wilkes County, Ga was likely a cousin to the slain Allen Spurlock. The children COULD have been children of the slain Allen as John was quite old to have minor children.
Use this only as a guide as none is really PROVED but we are getting close.
