PERSON, James, Capt., and wid. Frances Shackford [bet. Oct. 1748 and May 1749]. [Note: it is not clear what the date range is based on, but it is clearly invalid as the husband died in 1744, and per the Essex Genealogist article cited, Frances' will of 13 Dec 1745 described her as "widow of Capt. James Pearson, late of Haverhill, deceased" three years before the start of the specified date range.]
