According to "The Genealogy of the Worthington Family," by George Worthington (1894), Martha SEARING was born in Stillwater, NY on 10 March 1808, and was the daughter of Ursula WRIGHT and Nicholas SEARING.
Unfortunately, this is before NY state started recording births, and there is no vital record confirmation of this clue, nor have I found any church records of it yet.
Martha went on to marry Denison Worthington on 24 December 1829 in the 2nd Presbyterian Church of Albany NY. She had 3 children, Robert Searing Worthington (4 October 1830), Harriet Worthington (20 July 1833) and William Henry (23 May 1836). She died on 23 March 1839 in Albany and was buried with her two children who pre-deceased her, Harriet and William.
