• John Winthrop, who became the first governor of the Massachusetts Bay Colony, lived in Groton, only six miles from Sudbury, its market town. It appears probable that William Waterbury joined with large group of emigrants who sailed in the Winthrop Fleet to the New World. Mr. Winthrop and the other officers of the Company of the Massachusetts Bay embarked 8 April 1630 from Yarmouth, Isle of Wight, in the ship Arbella, arriving off Salem 12 June 1630.2435, p 495

• Emigrated with Winthrop fleet in 1630 and participated in the founding of Boston, Massachusetts Bay Colony, but records of him and his wife, Alice, are entirely lacking except for their membership in the Boston church.2435, p 498

• This William Waterbury had baptized in the church of All Saints, December 3, 1621, a son, John Waterbury. The father is the one whose name, entered as “Waterbury,” appears in the list of persons who agreed in February 1629/30, to sail from England in the following April for New England in one of the vessels of the fleet which brought over John Winthrop and the other governing officers, or “government” as they were called, of the Company of the Massachusetts Bay. Mr. Winthrop and other officers came in the Arbella, which vessel finally sailed from Yarmouth, Isle of Wight, on April 8, 1630, for New England. William Waterbury, when residing at Sudbury in Suffolk, was within five miles of Groton in the same county, the English home of John Winthrop, who became a founder and the first Governor of the Colony of the Massachusetts Bay. Sudbury was the market-town for Groton, and the principal rendezvous for the gentlemen and farmers of the countryside of southwestern Suffolk. Thus, one may see how William Waterbury became interested in emigrating in the Arbella or in one of the other vessels of the same fleet, with the head of the company, John Winthrop of Groton, who was doubtless as well known at Sudbury as was William Waterbury.
The names of the wives and children of the men who engaged passage in the company’s fleet in 1629-30 are not given in any passenger list. The Arbella arrived off Salem, Massachusetts, on Saturday, June 12, 1630; in August many of the passengers in the Winthrop fleet founded Watertown under the leadership of Sir Richard Saltonstall. The strange thing about William Waterbury is that he is not now of record in New England.2453, p 479

• The absence of any reference in the records of the court of the colony of the Massachusetts Bay to a settlement of the estate of William Waterbury, leads to the belief that he died after returning to England.2453, p 480
