I research Daltons. Currently I am workinhg on the desfcenbdants of the above couple in S.E. Missouri ca 1820-1900.
I have several hundred of their descendants catalogued. I will help where I can.
I find it interesting that in Madison County, Mo. 16 July 1867, Elijah Dalton married Mildred Sebastian. To me this indicates there was another Sebastian family in that area perhaps a nephew of Susannah. Any idea who ?
