William Brewster married Mary (whose maiden name is unknown) there is some speculation as to her maiden name, with the most common being Love or Wentworth.
The maiden name of William Brewster's wife has not been proven. The claim it was Mary Wentworth rests solely on the fact that Mary Wentworth happened to live somewhat close to William Brewster in Scrooby, Nottingham. That is very shaky evidence to say the least. Further, it has been proposed that William Brewster may have married Mary Wyrall, but the evidence is just as flimsy for that marriage. There are no fewer than seven marriages from 1590-1610 that have been located in parish registers showing a William Brewster marrying a Mary. All, however, have been satisfactorily eliminated as probable candidates for the William and Mary (Brewster) who came on the Mayflower. So at present, there is no evidence to document who William Brewster's wife Mary actually was.
