Walter Tybott, son of Walter and Elinor Tybott, was born in 1584 in Chepstow, Monmouthshire, Wales. Walter married Mary, whose maiden name is, as yet, unknown, in 1620, most likely, in Wales. He, and his family, including his parents, were among the early Welsh Puritans accompanying Reverend Richard Blinman of Chepstow, who was called by Massachusetts Bay Colony's Governor John Winthrop to be the colony's preacher in what would become Marshfield, Massachusetts. However, Blinman disagreed with the views of the other Pilgrims in Marshfield, and he, and his followers, migrated to present-day Gloucester, Massachusetts. Walter died on August 14, 1651, in Gloucester, Massachusetts, at the age of 67, and is buried in the First Parish Burial Ground in Gloucester. There is no stone existant.
