Hello Joan: I think that my ancestor Peter Sand (born circa 1813 in Luxembourg) is the Peter Sand that you mention in your posting. He was married to Angelica Steltz and they had nine children: John P., Michael, Nicolaus, Anna, John, Kate, Peter, Joseph and Maria. I am descended from their daughter Anna who was married to Michael Stienbauer of St. Cloud. If you or your mother have any information on any of them, I would love to hear it.
