Since this posting I found that Lucinda b. 1809 who married Alvah Benton is the d/o Issac Earle and Sarah Wilson. Isaac was the son of Daniel Earle Jr and wife (first wife, her name not yet determined). Issac died in November 28, 1833 and Sarah/Sabra died December 25, 1837, both are buried at Dresdan, Wash Co NY in South Bay Cemetery.
Daniel Earle Jr did have a dau namedMary aka Polly but she married Phineas Saunders and she died December 21, 1860 @ Whitehall, NY. There are ALOT of Earl/Earle/Earles, who are related to this Daniel, his siblings, etc in both Wash Co and Onondaga Co NY. Your Polly may be one of the daughters of this Daniels siblings?
Sorry I couldn't help you further...but check into those areas as well.
