Allen, Cobb, Jones, and Green family connections

I noticed there are many Allen descendants on the forum. I have a Elizabeth Allen born about 1700 in New Kent ? who married Robert Cobb. Their daughter Sarah Cobb married Robert Jones of Brunswick, Va. about 1737. Then had a son William Jones was born in North Hampton then his son Edward Jones married Rebecca Green and lived in Granville Co. NC. The next daughter Hannah Jones, my 4th great grandma, I have family notes that she is of Indian blood but unknown. Does anyone know anything about this line, specifically Elizabeth Allen?
