I tried to help you, but couldn't find your brother at AdoptionRegistry.com or Peoplefinders. Then I ran a Google search and found his name in a query posted by Trish:

http://64.233.161.104/search?q=cache:u_QrgIJY9MMJ:www.geneal...

I assume you are aware of her query. If not, you can take a look at it.

Good luck from Reg Niles
