I called Paul Alfred Elmer, Grandson of Peter and Katharina Kerber, in the late 1970s to ask if he may have heard anything of the family history that may be helpful in my research. He was so kind and happy to hear from his brother, Herman's grand-daughter. He told me that his parents just never normally talked about those things, but he did remember three things that became my clues to research:
On the Family Tree Page you will find their descendant's pages with all of the information that I have been able to gather over these years.
I've put some good research websites in LINKS and will add more as I find them. As a family historian, I'm always wondering why. One answer leads me to more questions.
