The Dutch explorer Adriaen Block explored coastal Connecticut in the Spring and early Summer of 1614 in the North America-built vessel "Onrust". The first European settlers of the county, however, were Puritans and Congregationalists from England. Roger Ludlow (1590–1664), one of the founders of the Colony of Connecticut, helped to purchase and charter the towns of Fairfield (1639) and Norwalk (purchased 1640, chartered as a town in 1651). Ludlow is credited as having chosen the name Fairfield. Fairfield is a descriptive name referring to the beauty of its fields. The town of Stratford was settled in 1639 as well by Adam Blakeman (1596–1665). William Beardsley (1605–1661) was also one of the first settlers of Stratford in 1639.
