Ancestry.com has helped me find my dads birth record which shows his first name IS NOT his name. It was Geraldean, and he not legally, changed it to Geral Dee. I also found out a few months ago that my favorite aunt in the world that died when I was 10, who was my moms only sibling who my mom said she loved so dearly, and was devastated by her death; "IS BURRIED IN AN UNMARKED GRAVE, beside her mother, my grand mother.
Ancestry.com cost 135.00 a year but, well worth it. You can complete your and your spouses family tree going back 45 or more generations in less than one year. Ask all family and friends because I have found out over the past three years that they all or most all, know and have ALWAYS known.
