Hello everyone- just thought I would put my little pearl of knowledge out here also.
My great great grandmother is Catharine Leva (maybe De Leva). The only thing I know about the family is that she married Francis (or Francois) Sotiér on August 10, 1863. At one point my grandfather was under the impression (family rumor) that her father was a French General (????).
I searched Ancestry.com using the name Leva and found several St. Louis marriages around the same time period. (Anna Leva, Christian Leva, George Leva).
