My ancestor, R. S. Snell married Louisa Robertson, Nov. 20, 1833 in Nashville.
Their children, all born Nashville: Cornelia 1836 William T. 1841 Frances M. 1845 Laura M. Feb. 16, 1848she married Hugh McNary Cadwell Dec.08, 1866 in La Grange, Fayette County, TX. Their daughter, Frances Norvell Cadwell was my great grandmother.
On LDS file Walter Poage Remington listed R. S. Snell as a relative.
In another search I found Robert Robertson married Loisa Sugg..maybe Louisa?. Robert Robertson was the son of James and Margaret Poage Robertson.
