Hi,
thank you so much for taking your time to provide all that helpful info and links. I'll look at all of them. As the US son of that Erwin Heinz Kuhoff has no money at all, his sister will have to pay for any records. So I'll forward your info to her. She is a native speaker and can ask for the records and look at the links as well.
Thanks again on behalf of Ricky nee Kuhoff adopted by US military people from Germany in 1956.
Gaby
