Hello Roberta, Sorry if this gets confusing. I refer to Ellscheid but have reason to believe we are looking for information on the same person or family.
My mother explains that there are two men with the name Robert Ellscheid that we know of.The first one I mention is her father, he passed away in Koln, Germany in 1991 at the age of 61 making him born around 1929/1930 (I realize you are looking for a Robert that was born around 1921 but it still seems so close).He was found in a hotel that he was believed to have lived in. Anything unusual about him?Well he was often between Canada and Germany. In Canada he fatherd 2 children with a woman by the last name Sandusky as well as 4 with my garandmother. It is very possible he was a father to more. These specific children were born 1954 and on.This Robert is the son of Klaus/Claus Ellscheid.
The second Robert is Klaus'brother.He would be the first Robert's Uncle.He was a lawyer and a professor. I think he's a bit to old for your search because he was born about 1900.The thing is, it would make perfect sense if he had a son at the age of 21 and named him Robert Jr.?! and maybe this son was "switched" to Alshire.
Hopefully this is of some help.If you have anything that even sounds slightly familiar, please let me know.I have a picture of the first Robert Ellscheid in his younger years. If nothing else, it would be interesting to see if there is any kind of resemblance.
I know some more "quick facts"but would like to make sure we are on the same track.
