I found her marriage record to Peter (born Petrus) York. I know based off of DNA and the timeline involved she is my ancestor. But I cannot find record of her birth, her parents or who they might be, any previous marriages or later ones, or her death.
Only Ancestry, with its plentiful unsourced trees, has a family for her... that I know is wrong because every other tree with the same records has that Esther Simmons in the Carolinas.
She married Peter York in 1808 in Ulster County, New York, so I'm guessing (read: hoping) she was 15 or older at the time of her marriage... so I'm guessing she was born 1793 or earlier.
