Could this be him? Is he around 79 years old? This man was in Boonsboro and it appears his relative his Helen. If this is him, I'm sorry to say it appears he passed away:

Run his name and birthdate at the link above and it will show Robert Allen Fisher, born 9/18/31 passed away 3/7/10. Last address of record was Gainseville, FL. His SS# was issued in Illinois.
