Going through my Alderfer book and it states that he first married Magdalene Acker marriage date April 7, 1766
So her date of birth can not be correct. It states that she had 3 children
John Altdoerffer b. Feb 14, 1770
George Aldoerffer b. Mar 22, 1772
Salomie Altoerffer b. Mar 27, 1776
He then married Magdalene Jacobs November 13, 1806
There are two husbands listed I do not believe that the merge is correct. This family lived in Virginia not in Macungie
While I do not have a date of birth for either Magdalene's I do have marriage dates so I am removing her as wife of Frederick Altoerffer also her first son was born before this Magdalene was born.
