One neat place to get copies of ancestral signatures is from releases written on recorded copies of mortgages. This signature is actually for my step 3rd great-grandfather when he released the mortgage from his step-daughter and her husband in 1879.
We'll be mentioning this family and some of the records in an issue of Casefile Clues after the first of the year. We've mentioned Barbara before, but these transactions center on her
third (or second) husband. I first learned of these deeds years ago before I knew very much about the family. Now that I have a context in which to put them, there's more of a story than I initially thought.
