United States Connecticut Western Reserve
By virtue of their "sea to sea" charter, Connectictut visionaries once claimed parts of northern Pennsylvania, northern Ohio (especially the Western Reserve and Firelands), and southern Michigan, northern Indiana, northern Illinois, and even further west.
Connecticut settlers in present-day Pennsylvania contended for Connecticut's rights in the Wyoming Valley from 1769 until 1799 when they were finally granted Pennsylvania legal titles. For further information about Connecticut claims and connections in Pennsylvania see Westmoreland County, Connecticut.
Most of the eastern states ceded their western claims to the federal government in 1786 in exchange for federal assumption of the states' Revolutionary War debt. The exception was Connecticut's Western Reserve.
The Connecticut Western Reserve or "New Connecticut" was land claimed in the northeast corner of Ohio (at the time part of the Old Northwest Territory). The western half of the Western Reserve was set aside as "Firelands" or "Sufferers Lands" for Connecticut residents burned out by the British during the Revolutionary War (only a few ever moved there). In 1795 even before she had clear title from the Indians, Connecticut sold the remaining eastern half to eight Connecticut citizens who had formed a land company. Land company surveyors set up townships with five miles on a side rather than the standard six miles on a side in the rest of Ohio. Settlers trickled in and founded towns: Youngstown in 1796, Warren in 1798, and Hudson in 1799. Finally in 1800 Connecticut ceded her Western Reserve claims to the Northwest Territory.
