David was definitely married to Esther Bently, per Will and Probate record for her brother Ezekiel Bentley, June 1832. According to our ancestor, Margaret Bently Thiers, William did marry first Experience Greeno.
The mother of these Bentleys, Olive Hopper Bently was married 2nd to Oliver Greeno. I obtained a copy of the will of an Oliver Greeno, dated 1865, probate 1867, so this is either a son of Oliver or grandson (possibly son of David and Esther because he has land that was once part of Bently Farm).
If you are interested in children of this Oliver, let me know
