The same story is in the front of a genealogy I have that was compiled quite a few years ago - perhaps in the 1970's by Madeleine Rummel. However my own research on ancestry.com indicates that the ancestor who came from Germany was Heinrich. My maiden name is Zumbrum. Some of the family spelled it with an "n", some with an "m".
I have a public tree on ancestry.com. If you care to send me your email, I'll send you an invitation so you can view my tree.
