The Mordecai Abraham of King William County was likely a grandson of the Senior. I know the Mordecai Abrahams of Powhatan County was a grandson of the Senior, he was my 2nd great grandfather. I don't believe Levi is any relation. Do you have interest in the Abrahams formerly of King William County? All of my information is in the Virginia State Library in Richmond as well as several Historical Societies close by.
