I have an Esther Ackerman, daughter of James Ackerman and Easter/Esther Marshall. She was born about 1791 most likely in Saratoga, New York. That is where James is in 1790 and 1800, so it might be safe to assume that's where Esther was born. She married David Thayer 27 Dec 1811 in ?? New York. That's the extent of what I have on her.
