That could be a possibility, that Peter Adam, Daniel and Michael were brothers. I had thought of that too, but thought I would start with father. I have a new lead to follow. Their father may have been Michael, possibly married to Anna Margarette. I did not have a birth date for Peter or Daniel, so was not sure of their age upon arrival in Philadelphia. My records show both Peter and Daniel arriving 19 Sep 1749 and Michael arriving in 1751. I have a marriage confirmation of Peter and Elizabeth Kiefferin through church records. Thank-you for the interest.
