joyce, I have listed in my family tree software an Elizabeth LeMarr born 5/3/1841 in Jefferson County, TN. Married Robert Julian Barnwell in Fawcett Platte Co., MO in 1866. Elizabeth was born to Mary LeMarr with 4 other siblings that we think are illegitimate. Partners name was Montgomery? The MO wedding may tie these together. I have no children tied to Elizabeth and Robert but don't know if this is correct.
