Ostendorf Family Genealogy Forum
I sent you an email message with my address. I hope you got it. I also gave your info to my brother, who was very excited to hear that you have a whole other generation documented prior to Clemens and Clara. We were always under the impression that Clara's maiden name was Bankloh. Also, we thought that Ralph went to live with his older sister, Emma, after his parents died. My mother remembers my grandfather talking about Aunt Bertha. I guess when he said "sister", he meant Clara's sister, not his sister.
Regardless, you've provided a lot of missing pieces for us and cleared up some misconceptions. My brother, Gary, I'm sure will be contacting you soon.
