I am looking for any information on Jacob Beilstein/Boylestone from the Hesse Darmstadt area of Germany. He died in 1791 in Lancaster County, PA., USA. His wife's name was Sophia, she died in same place in 1796. I am especially interested in Sophia's maiden name. Her will states that her sister's daughter married my ancestor John Myers. I trying to find my ancestress's maiden name. Any help would be appreciated. Thanks.
