Don't give up! I recently was "found" by a cousin I didn't know I had! Her biological dad is my first cousin. She had been looking for that half of her heritage for over 20 years. Thanks to the internet, and a mutual distant relative, we found each other. I was able to send her the family tree, copies of old photos of her great-great grandparents, family recordings (they were fairly well known country singers, and made a recently discovered informal jam session record in 1944), and a few trinkets that had been her great-grandmother's. So, after all her diligence, she now knows about her paternal side, and I have a new cousin and friend! Here's another true story. Two people I know had a child when they were teenagers, and gave him up for adoption. This couple later married, had several children, and began a search for their first child. Unknown to them, he was also trying to find them. It took them years to get through all the red tape, but they finally found each other, and the young man was able to re-join the family of his parents, brothers, and sisters. So never give up, but also remember, your grandfather may have a very good reason not to want anyone to make a connection. In my new cousin's case, her father is not a good person. She is much better off without him in her life. But that doesn't stop US from having a close relationship! Just prepare yourself for the bad side of it as well as the good. Sometimes the ending isn't a happy one. Good luck, and God Bless You. I hope you find her, and it works out well for all of you. Diane in OH
