Census Information for Henry County IL

Submitted by Susie Martin-Rott

Who held Illinois at what time? To best use Federal Census information, it is helpful to know where Illinois was enumerated over the years. Here's a little chart to assist you.

Year Who Controlled Illinois
1680-1763 Settled by France
1763-1783 Great Britian
1783-1786 Connecticut, Massachusetts and Virginia
13 Jul 1787 Northwest Territory
04 Jul 1800 Indiana Territory
01 Mar 1809 Illinois Territory
03 Dec 1818 State of Illinois

State Census Information

1810-1860 Indexes The only complete State censuses during this time period are for 1820 and 1855. Lists only head of household and head count of total number of family members. Does NOT list individual family member names except that of the head of household. Uses the same format as pre-1850 Federal Census records.
1810 Randolph County
1820 Edwards County missing
1825 Edwards, Fulton and Randolph Counties
1830 Morgan County
1835 Fayette, Fulton, Jasper, Morgan, Putnam and Union Counties
1840 Adams, Bond, Brown, Calhoun, Champaign, Clark, Clay, Clinton, Coles, Cook, Crawford, Edgar, Effingham, Franklin, Fulton, Hamilton, Hardin, Jackson, Jasper, Jo Daviess, Johnson, Knox, LaSalle, Lawrence, Livingston, Monroe, Randolph, Rock Island, Schuyler, Stark, Tazewell, Union, Vermillion, White and Whiteside Counties.
1845 Cass, Madison, Montgomery, Putnam and Tazewell Counties
1855 Schedules are missing for Carroll, Champaign, Franklin, Gallatin, Henry, Jefferson, Lake, Stark, Will and Woodford Counties
1865 Schedules are missing for Gallatin, Mason and Monroe Counties. The Henry County filming, at least the one I rented, shows that many pages were heavily damaged prior to filming. Many of the pages are so badly damaged that only a few names at the bottom of each page are legible.

Soundex Indexes
1880, 1900, 1910, 1920 only
The Soundex is an index based on the phonetic makeup of a Surname. Surnames that sound the same, but are spelled differently, like SMITH and SMYTH, have the same code and are filed together. Surname, given name, age, sex, race, enumeration district, city, county and state of residence, others in household, including the relationship, page and line number in the original census record were taken from the census and placed on a card, then "coded" according to the phonetic makeup of the surname. To locate the soundex code for the name you are interested in you may use the National Archives "Soundex Machine" at http://www.nara.gov/genealogy/soundex/soundex.html 

1880 is missing 1000 "O" cards and did not list children under age 10

1890 was not indexed due to fire

1910 only 21 states were done (Illinois is one of them) on a soundex/miracode system.
