Hi Pat,
My brother Bill Powers wifes maiden name is Sesma. Helen's family is from Casa Grande AZ. My newphew Billy and I were just discussing this last night. He read somewhere recently his mom's family someone founded Abilene, TX and somone in the family is how Sesma, Spain is named they are from over there.
I do the family history in my family, I've been working on it since I was 15 back in the late 1970's. I'd love to hear more about my sister in law's family and give my grown nieces and newphews info for them and their kids.
Look forward to keeping in touch with you.
Tricia
