This evening I had some time to check my database and other Information. It may be I found the the father of Ralph Paul Eugene: I may be it is Albert born 30. May 1879 in Calmar, Winneshiek, Iowa as written in US Census from 1880, but it can be Quakenbrück, Prussia too.
Perhaps you find there now more information, because Calmar was a longer time a home of 3 brothers.
