I have researched my wife's ancestors back to Ulrich Rieser, immigrant. He also had a brother William who came over with him. I believe he had another brother Phillip, based on a loan in the will of William, who also came over at about the same time. Do you have any info on the siblings of your John, or any info on where in europe he came from, ours indicate possibly Switzerland. My e-mail address is email@example.com.
