Nicole, There were two Alderfer men who came to Ammerica in 1732 and 1733. Both were named Frederick and as far as I can tell both came from Aldorf, Zurich, Switzerland. Both came on a ship named Samuel, with the same captian and to Philidelphia. If they are related I do not know. I have a large numer of Altafers in my family history let me know more about your ancestor and I will be happy to help you if I can.
