Dicey Eakin was the daughter of Alexander Eakin and Margaret Kennedy. She is mentioned in Alexander's will. I have placed his will up on We Relate Wiki.
Alexander Eakin belongs to the Eakin Clan from Berkeley County W. VA / Greene Co PA. There is a will for James Eakin, Berkeley Co in 1765 that list children and his brother Thomas.
The Berkeley County Eakin Clan is I believe, distantly related to the Eakin Clan of Augusta/Rockbridge County.
