Sorry. I checked my Nichols' descendant chart and found no David. Anthony Nichols m. Alice Greene dau. David Greene, so it is not unseemly that they had a David but my chart lists other children. They were Vermonters. Also, my lines are Reynolds and Greene -- of RhodeIsland. The Nichols' I encountered intermarried with both as the three surnames are among the first settlers of Providence under Roger Williams. (frequently, Williamson and Williams are interchangeable.) Also, the Greenes and Nichols' were, generally (not always by any means) Quakers.
