Not sure if you got my PM here or on FB. If you'd like a link to the adoption group I go to; PM me.
If your brother was told he was adopted; it's possible he's going to order a family tree DNA kit from
23andme. It's the cheapest one out there & has the largest database. A LOT of adoptees are doing it to try to find their birth parents. You as well as your dad or male sibling should submit one in case he tries it. I'll copy a post on an adoption site to explain how to get your DNA into other sites as well...
There are groups of
DNA search angels who will help you and educate you on how this works so you can then help others. People are finding their relatives every single WEEK~! do 23andme.com $99 and once you have those results upload to
FTDNA (Family tree DNA) for about $99 and to
GEDmatch and a DNA Tools site
DNAgedcom.com both free.
