Anna Sylvester mar. James Lowrey Culbertson in 1869 in Vincennes, IN. They had 3 children die in their first year. Then they had twins, David Franklin Culbertson and Susan BOAS Culbertson (dob Aug 1878). The middle name of BOAS was the first time it appears in the CULBERTSON family, so it must come from Anna Sylvester's family.
The Culbertson family is from Edwardsport and Vincennes, IN. James L. Culbertson was 1st mar. to Ann Ross. They had several children.
Anna (Sylvester) Culbertson is my great grandmother, but I know nothing about her and her families.
