My suggestion is to try using just the last name to find such an unusual first name. It's possible that as soon as he could, he changed it. Hopefully you have some dates to use in conjunction with the last name, a wife or family names that might get you the connection you hope for. Perhaps someone else has heard it and can suggest a nickname that he might have used.
Good Luck with your search. Have you been in touch with the Godfrey Library?
