Hello,
I just found your inquiry on Rootsweb. Henry Rabe is my great great uncle. (The son of Joe and Fredericka Rabe) I have an Ancestry tree with some family information, but I am not sure of exactly what info you are looking for.

I would LOVE to know the maiden name of both Henry's wife and Henry's mother, Fredericka. I think it may be Fredericka Priem Rabe, but I am not sure. Do you have any information?

If you would like, please email me.
