I was working on some of the family lines connected to my Harris line. I noticed while looking at the Parker family that they also have connections to the Alston and Hunter families.
Two of the grandchildren of Richard Parker III and his wife, Elizabeth King. Their parents are Elizabeth Parker and Isaac Hunter, Sr. They are: Jesse Hunter who married Ann Alston Isaac Hunter who married Martha Alston.
I don't research these families, so this is all I know.
