That's not right. It was the shoemaker who returned to England and the blacksmith who stayed put. Anderson has them reversed. (Anderson, like every genealogist who ever lived, does make mistakes.)
According to the source cited on the profile (and that Anderson references in GMD), "By 28 July 1649, Henry Chamberlin, shoemaker, had returned to England leaving no known surviving issue in the New World; Henry Chamberlin, blacksmith, remained and left numerous descendants." Donald Conrad Chamberlin Sr., "'The Two Henry Chamberlins of Hingham, Massachusetts, 1638-1649," in The New England Historical and Genealogical Register, volume 139 (1985), at page 126. (Emphasis in original) At page 134, the author cites a deposition made by “Grace Chamberlin the wife of Henry Chamberlin shoemaker” stating that he had returned to England and also a deed made in 1675 in which the co-executors of the will of Henry Chamberlin sold property that Henry Chamberlin, blacksmith, had acquired over the years in Hingham.
Edited to add: I hadn't noticed the Anderson had them reversed; I'm going to add that to the "Disambiguation" section at the top of the Biography.
