I am curious as to your grandmother's ancestry. Yes, we do have lots and lots of Dillards and Richardson is used as a given name several times in our family.
My gggg-grandfather is William F. Briant of Spartanburg, SC who migrated to Alabama in the 1830s. His son Coleman married an Elezene Cohen(Cohn) who is rumored to be half Cherokee indian. I have been searching for her ancestry for some time, but am not having any luck. The records that I have show that Elezene and Coleman married in SC. She was born in 1823.
How did you confirm your great grandmother was an Indian? Are there records that I need to look for specifically?
