Being a history of the descendants of Richard Dexter of Malden, Massachusetts, from the notes of John Haven Dexter and original researches. Richard Dexter, who was admitted an inhabitant of Boston (New England), Feb. 28, 1642, came from within ten miles of the town of Slane, Co. Meath, Ireland, and belonged to a branch of that family of Dexter who were descendants of Richard de Excester, the Lord Justice of Ireland. He, with his wife Bridget, and three or more children, fled to England from the great Irish Massacre of the Protestants which commenced Oct. 27, 1641. When Richard Dexter and family left England and by what vessel, we are unable to state, but he could not have remained there long, as we know he was living at Boston prior to Feb. 28, 1642.
