I haven't found conclusive documentation on this George's parents. I'm helping a friend with her lines on Geni and I see that Wiki has his father as John but other sites have no parents listed for him at all.
The only Ancestry tree I found with parents listed shows:
George Allen
BIRTH Abt. 1720 Hanover Co., Virginia
