Richard Nevitt was warded to John Saunders of Peter and Paul's wharf. He owned with Thomas Cornwalys, one fourth of the Dove, a fifty ton small pinnance contracted by Lord Baltimore who owned the remaining shares, as tender for the voyage of the Ark of London to the Calvert's palatinate of Maryland with the first colonists. John Saunders, with his ward Richard Nevitt signed on for transport to Maryland and were passengers on the Ark when they left London in late October for the Isle of Wight. The two vessels left Cowes on November 27, 1633 and after an initially difficult passage went via Barbadoes to the Chesapeake Bay. They first disembarked formally at St. Clements Island in Maryland off Breton Bay neck on March 25, 1634 the first day of the English Julian year.

The best account of the voyage of The Ark and The Dove and the background of the founding colonists is given in The Flowering of the Maryland Palatinate by Harry Wright Newman of Washington, DC, 1961.
