Billy or Bruce - Help ID

This is reported to be a pic of my half-brother b. Bruce Conley ca. 1945/6 in E. KY but raised from birth by a Louisville area family. They may have called him "Billy".
Went to all-boy's school, father (adptd)was retired military. Last name may have began with a "T". Billy moved to NY reportedly ca. 1980 and no info since. Rumor of passing. May have resided in Indiana buy am reasonably certain on the louisville area.

Any info better than almost none! What surname was he raised with ... did he use? What school? Is this really Bruce or Billy? If not, my apologies - got this pic from an aunt who remembers him at birth.
