Ralph Schrammeck, again.
I see in reading over your query again that you do have the names of Leopold's parents. We do not have Henry's parent's names. If Johan Schrammeck and Katharina Rohonsky do turn out to be his parents we would be overjoyed! I think it is interesting that Henry named two of his sons Walter and Leo. This could mean that he was naming them after some one in his family, his brother Leopold and someone else that your grandfather, Erich Walther was perhaps named after. Please let me hear from you.
