My info from the Doty/Doten family pub. 1897, do not keep a file -would not have space. There are 6/7 Cornelius in index, do not see a wife with family name of Mc Cumber.See 2 marriages of Doty daus. with the Mc Cumber family.Need to know dates & locations, there was aCornelius that married a Mary Ann (Mnu) -children born 1790+, no Sarah listed.Don't remember what my reply was to the original Sarah query, but looking in the book, the names & locales seem to indicate that she was of dau. of John, who was the next younger brother of the Cornelius that m. Mary Jane.
