A certain "Master Williamson," whose name and presence, though but once mentioned by Governor Bradford, have greatly puzzled Pilgrim historians, seems to have filled this berth on board the MAY-FLOWER. Bradford tells us that on Thursday, March 22, 1620/21, "Master Williamson" was designated to accompany Captain Standish--practically as an officer of the guard--to receive and escort the Pokanoket chief, Massasoit, to Governor Carver, on the occasion of the former's first visit of state. Prior to the recent discovery in London, by an American genealogist, of a copy of the nuncupative will of Master William Mullens, one of the MAY- FLOWER Pilgrims, clearly dictated to Governor John Carver on board the ship, in the harbor of New Plymouth (probably) Wednesday, February 21, 1620 (though not written out by Carver till April 2, 1620), on which day (as we learn from Bradford), Master Mullens died, no other mention of "Master Williamson" than that above quoted was known, and his very existence was seriously questioned. In this will, as elsewhere noted, "Master Williamson" is named as one of the "Overseers." By most early writers it was held that Bradford had unwittingly substituted the name "Williamson" for that of Allerton, and this view--apparently for no better reasons than that both names had two terminal letters in common, and that Allerton was associated next day with Standish on some military duty--came to be generally accepted, and Allerton's name to be even frequently substituted without question.---Miss Marcia A. Thomas, in her "Memorials of Marshfield" (p. 75), says: "In 1621, Master Williamson, Captain Standish, and Edward Winslow made a journey to make a treaty with Massasoit. He is called 'Master George,' meaning probably Master George Williamson," etc.
