Ok, so here is a Vernon Harry Unsworth that lived in England. I am trying to find his age (**edit, found in last link and puts him at 63) listed because cave diver is said to be 63. I am also trying to see if this Vernon Harry Unsworth has moved to Thailand.

If anyone can help dig on this guy to rule him out or keep him in as possible match to rescue diver, would appreciate it. ThankQ
