Their children were: Marjery Deritha Monrovia Isabella Thomas Whitfield Marjery (my ggggrandmother) and Deritha married Anderson brothers and came to Illinois. Isabella married a John Morgan and Monrovia was committed to an asylum near Nashville around 1870. Any information would be most appreciated. Karla Jefferson
