Well, I got a response from my letter that I had written to the sister. She had given me a little more information and yes, we are related! Our grandfathers were brothers. She gave me an address and phone number to an older cousin who may know more family information.
I'm really excited and I have a 1st cousin who lives in the same town as the older cousin and she is willing to meet with her and help with the family genealogy.
I'm so glad that my mother and I sat and wrote down the family history together. Now there isn't anyone around to ask...the family is spreadout with most not knowing each other.
My mother gave me the names of all her siblings (10 total) their children and grandchildren if known, plus aunt uncles cousins. This was done years ago and the names match with what my newly found cousin gave me. It's so important to do and takes little time.
