Pennsylvania County Research Guide

Erie County, Pennsylvania

Formed March 12, 1800 from Allegheny County and organized in 1803 — county seat Erie. Who settled here, why families moved on, and where to look for their records.

Who settled here

Pennsylvania obtained the Erie Triangle in 1792, after New York, Massachusetts, and Connecticut gave up their claims to the federal government. Competing claims slowed settlement. The conflict between settlers under the Connecticut Land Company and those who came under the 1792 act became known as the “Actual Settlement War.”

Early settlers named in a county genealogy include John Vincent, Rufus S. Reed, Judah Colt, Elisha Marvin, and Henry Loomis. Connecticut kept the Western Reserve in Ohio when it gave up its other western claims, and its Firelands, about 500,000 acres in what is now Erie and Huron Counties, Ohio, were given to Connecticut citizens whose property the British destroyed in the Revolution.

Why families moved on

Records that say exactly why a family left are rare. Treat these as leads, and look for evidence about your own ancestors in deeds, tax lists, court cases, and church records.
