John Bradford was born 1618 in Leiden, Zuid-Holland, Netherlands to William Bradford (1590-1657) and Dorothy May (1590-1620) and died 21 September 1676 Norwich, New London County, Connecticut, United States of unspecified causes. He married Martha Bourne (1614-) 1640 .
Despite being their only child and only about 2 years old at the time, John did not travel with his parents to Plymouth Colony on the Mayflower and thus is not considered in history as one of the Pilgrims. He remained in Holland with his maternal grandfather.
