Pamela, I agree about what stories a person can believe or not. Actually my father told me that my mother was a Native American. Then when I was 33 or 34 I had to fly to Oregon to meet, and bring my grandmother back to Texas. There was no doubting her, she looked Indian and it was a shameful thing as far as my mother was concerned. My grandmother lived with my family for three years before she died. Until then I had always hope I was adopted, but even I could see I looked like her.
I tried Ancestry.com for a year, but I'm not computer literate, nor could I grasp how to search for the right data.
