Adoption Question

Can you help? 

How can an adopted child prove the relationship to a birth mother?  Mother and child are in contact with each other.  Neither one of them is against proving the relationship.  The birth was in Connecticut and the adopted child still lives in Connecticut. 

Suggestions?  Thank you. 

SCGS Jamboree - In THREE weeks

Three weeks from now I'll be at Jamboree in Burbank, California.  (It's sponsored by the Southern California Genealogical Society.)  I'm excited.  I know I'll see familiar and new faces.  It's not too late to register.  http://www.scgsgenealogy.com/Jamboree/2012jam-home.htm.  Yes, that's where you'll find all of the information.  Hope to see you!!!
