The typical requirement for release of vital information is, the person must be at least 100 yrs old. Researching the 1960's is not impossible but requires specialty methods. Unless some one on Wikitree is researching your Gary, and here I am assuming you have searched the Wikitree profiles, your chances of getting an answer is very slim. We would like to help. Have you tried the Armstrong Family Genealogy Forum? Posting there would give you a good chance of finding a family member with information.
