I looked back through my thesis notes--amazing I still have them-- and found a copy of a statement (family history of sorts) made in 1949 by J.P. McCord (youngest son) in which he lists J.E. and Sarah Mooney McCord's children and their spouses. Louclement is shown as marrying T.B. Gillespie. Of course, that does not mean she might not have married your great uncle later, or first for that matter. None of the girls are shown as marrying a Thomas Walker Kilmer in this document.
