Joshua Harrington son to George & Abial Harrington born ye 28th Feb'y : 1725/6.
Source:Weis, Frederick Lewis. Early Generations of the Family of Robert Harrington of Watertown, Massachusetts, 1634, and Some of His Descendants doesn't give any marriage for Joshua and only says he was "liv. 1760", the date of his father's will. The father had moved to Brookfield, and his will identifies the father as "George Harrington of Brookfield", so the Joshua Harrington of Brookfield mentioned in the marriage record is likely his son. The will gives Joshua the farm "near the Spencer line", and Spencer VRs say that Joshua Harrington had three children (names not specified) baptized in 1759, so it does appear it was he that married in early 1754.
