Railey is her maiden name.Sorry for the double spellings.I was copy/pasting something my cousin had asked me and didn't notice that.
Her married name is Adcock.She married Carter Adcock, born January 1, 1801 in Buckinghame, Virginia.They married on Oct 9, 1817 in Sumner, TN.He died Nov 16, 1877.They had 12 children.She died March 16, 1877.
This is all based on research my cousin did a number of years ago and she is also on a bunch of different people's "tree" on ancestry.com.
I am descended from her via Carter Adcock.
I am VERY new at researching genealogy.I appreciate your patience.
