Marggie Carbis
Dad heard from the library in St.Louis and they sent on a copy of the marriage record of Henry Kerlin and Margaret Carbis.
Unfortunately, there is no information which decisively links these two people to Sam Kerlin, although I do believe that they are his parents.
I have just sent in a request to the Archdiocese of St. Louis, asking for a copy of the marriage certificate.
Perhaps that might provide the missing link.
Close up here.
