New London County, CT
History
New London County was one of four original counties in Connecticut that were established on May 10, 1666 by an act of the Connecticut General Court, which states:This Court orders that from the Paukatuck River wth Norridge to ye west bounds of Homonoscet Plantation shalbe for future one County, wch County is called the County of N: London. And it is ordered that the County Court shalbe held at N. London the first Wednesday in June and the third Thursday in September yearly.
New London County in 1666 consisted of the towns of Stonington, Norwich, New London, and Saybrook. The "Homonoscet Plantation" was settled in March 1663, at first as Kenilworth; but it was 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 in New London County in 1697, and incorporated as Plainfield in 1699. By 1717, more towns were established in northeastern Connecticut and added to New London County between the Quinebaug Valley and the Rhode Island border.
Windham County was constituted from Hartford and New London counties on May 12, 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.
