Thanks for the message and suggestions. The children of the parent immigrants are all still living and are in their 70's, all US Citizens. The name change my grandmother told me about. She also said their first names where changed when they immigrated. She is notorious for getting things wrong but I know their name did change. I am just unsure why or how. The letter for some reason did not attach but it is now. It was written in the 1970's and spells the names as they currently are spelled.
