Before Lake County existed

Lake County was formed in 1840 from Geauga and Cuyahoga Counties. For records made before then, search the parent counties:

Land: Connecticut Western Reserve

All of Lake County lies in the Connecticut Western Reserve, land Connecticut kept when it gave up its western claims, sold privately through the Connecticut Land Company. There are no federal land patents here, so start with the earliest deeds at the county Recorder (or the parent county's Recorder).
