I am the ggg granddaughter of Anna Kraemer, who is the daughter of a Peter Kraemer b.1782 and Maria Margarethe Alfelen b.1785. Very possible these are the same people...I just didn't know Anna had a sister. I know she had two brothers, Anton and Heinrich. Any of these names ring a bell?
Anna Kraemer m. Franz Alexander Preisser
son, George Preisser m. Mary Ann Cleary
daughter, Anna Elizabeth Preisser m. William Burns
daughter, Mary Elizabeth Burns m. Frank SanHamel
Those were my grandparents...
