Lake County was Established on March
1, 1839 and named for Lake Michigan
From the Historical Encyclopedia of Illinois, 1901
"Lake County, in the extreme northeast corner
of the State, having an area of 490 square miles, and a population (in 1900) of 34,504. It was cut off from McHenry
County and separately organized in 1839. Pioneer settlers began to arrive in 1839, locating chiefly along the Des
Plaines River. The Indians vacated the region the following year.
The first County Commissioners (E. E. Hunter, William Brown and E.C. Berrey) located the county-seat at Libertyville,
but, in 1841, it was removed to Little Fort, now Waukegan. The county derives its name from the fact that some
forty small lakes are found within its limits. The surface is undulating and about equally divided between sand,
prairie and second-growth timber. At Waukegan there are several manufacturing establishments, and the Glen Flora
medicinal spring attracts many invalids. Highland Park and Lake Forest are residence towns of great beauty situated
on the lake bluff, populated largely by the families of Chicago business men."
