The second group of Quaker missionaries to leave England for New England sailed on the small ship "Speedwell". Robert Locke was the master, and the passenger list, dated at Gravesend on 30 May 1656, included 40 names. The names of eight passengers were marked with a 'Q', indicating that they were Quakers and signifying that officials in England were already concerned about the religious fervor of these people. Holder, aged 25, was one of the eight, whose home was given as Winterbourne and another was his companion, John Copeland, aged 28, from Holderness.
