Lynn, When I posted this first query, I only had these names from a death notice for David E. Sweigert/Sweigard. I have just returned from a trip to Harrisburg where I found some additional information on both Brandt and Sweigert.
David E. Sweigert/married Sarah A. Negley
David's parents were David and Susanna Eschelman/children: John,Catherine, and David
David died in 1847, and Susanna married in 1848 to Samuel Brandt who also had children: Aaron, Harry, and Mary. I do not know Samuel's first wifes name. I still need to do alot of research, Let me know if this is the same family. I have a new email address Trish645@hotmail.com
