History
Henry County was named for Patrick Henry, a lawyer, orator, and statesman of the Revolutionary period, a member of the Continental Congress, and Governor of Virginia.

The county was established Seven Years after Illinois became a state from unorganized territory attached to Fulton County, Illinois on January 13, 1825. The original Henry County ran north to the border of Illinois and Wisconsin and included parts of present-day Carroll, Jo Daviess, Knox, Rock Island, and Whiteside counties.

In 1827, the formation of Jo Daviess County drastically reduced the size of Henry County to about half its present day area. The present borders of Henry County were not established until 1836, and until about 1837, Henry County was attached to Knox County.  The present county organization was completed in 1837.

Henry County has known four county seats, including:

1837–1839 Richmond
1839–1840 Geneseo—Temporarily appointed to house records.
1840–1843 Morristown
1843–present Cambridge
