In my research, I have stumbled into the Carver family of Carroll county.
I believe Charlotte Carver might be ggg-grandmother, but I can't be 100% certain of course.
She is listed on the census as being daughter of James & Ann Carver.
I have her as born in about 1836. I believe she married William Cross in 1857, I have a record from FamilySearch.org for a "Carloitt Carver" I have a Charlotte, William and Charlie Cross in 1860 in Carroll, TN. In 1870, I have the same 3 in Arkansas. She is listed as Charlotta in this census. In 1880, she is deceased and it is only William, Charlie and the rest of the children, including a Sophia Cross born in 1875. Sophia Cross was the name of my GGgrandmother.
I believe I may have the correct people. My gggrandmother Sophia's death cert. listed her mother as Charlotta/Sharletta and her father as W.R. Cross, both from TN.
Please reply if you have any information.
