Established in 1666, New London County consisted of the towns of Stonington, Norwich, New London, and Saybrook. The "Homonoscet
Plantation" referred to in the constituting Act was settled in March 1663, at first as Kenilworth but incorporated as the town of
Killingworth in 1667. Several new towns were incorporated and added to New London over the next few decades: Preston in 1687, Colchester
in 1699, and Lebanon in 1700. The settlements along the Quinebaug Valley were placed under New London jurisdiction in 1697 (later
incorporated as Plainfield in 1699). By 1717, more towns were established in northeastern Connecticut (between the Quinebaug Valley and
the Rhode Island border) and added to New London County.
Windham County was constituted from Hartford and New London counties on 12 May 1726, consisting of towns in northeastern Connecticut. New
London County lost the towns of Voluntown, Pomfret, Killingly, Canterbury, Plainfield, and Lebanon to the newly formed county. In 1785,
Middlesex County was constituted, consisting of towns along the lower Connecticut River Valley, taking away the towns of Killingworth and
Saybrook from New London County. Several additional boundary adjustments took place in the 19th century: the establishment of the town of
Marlborough in 1803, the transfer of the town of Lebanon from Windham County in 1824, and the transfer of the town of Voluntown from
Windham County in 1881.
