As shown by the Bridgewater VR birth entry that I posted upstream, Zerviah's parents were Jonathan and Rebecca Washburn. Rebecca was Rebecca Perkins - she married Jonathan Washburn 18-Jan-1757 [Bridgewater VR 2:388]. Finding Rebecca's parents is not easy - Mitchell does not show her in any of the Bridgewater Perkins families, and my initial attempts to find her met with no success. It is possible that she was a young widow, but I have not yet checked the VR marriage and death records for that possibility.
