Thanks so much.I know this took a lot of work for you and I appreciate it.I think the more of us working online on this the better--we'd probably get further if we could all share our information.
Just looking at my information of Elizabeth Allen Sanders (widow of Sion who wasborn 1807/8). I have her on the 1850 Leake Co., MS census living near her husband's sisters Lucinda Ragsdale and Celia Dulin. Also living by her is M. T. Sanders and Vinson Sanders, husband's brothers. Elizabeth has eleven of her children living with her on this census, ages 1 through 17 years.
I believe Elizabeth Allen was born in 1811 in Tennessee. I have parents for her: mother Mary Braxton and father Richard Allen.Does this correspond with your information?
