Leavenworth in his A Genealogy of the Leavenworth Family in the United States with Historical Introduction (Dodd C6163) has Thomas Leavenworth arriving in New Haven, Connecticut some time between 1664 and 1675. At time in the 17th century, however, a Thomas Leavenworth, ancestor of this branch of the Leavenworths, settled in western Connecticut and acquired and/or inherited considerable property prior to his death in 1683.
