Original marriage licenses for Cook County were destroyed by the Great Fire of Chicago on October 8–10, 1871. Marriages in the Illinois Statewide Marriage Index for Cook County prior to the fire were found in the Sam Fink Index. A copy of the Sam Fink Index is available on microfilm at the Illinois Regional Archives Depository (IRAD) at Northeastern Illinois University in Chicago. The only additional information that this depository can provide is the name of the newspaper in which the marriage appeared. FHL film 1321939 A microfilmed copy of the Index to Chicago and Cook County Marriages and Deaths Reported in Chicago Newspapers 1834–1889, compiled by Sam Fink, is also available at the Newberry Library (microfilm 608, general collections, 2nd floor.)
Community AreasThere are 77 individual community areas, as designated by the University of Chicago Social Science Research Committee. More than 200 neighborhoods are represented in the community areas. Community areas may have unique records available, or in some instances, their own newspapers. The Archival Collections at the Harold Washington Library Center, Chicago Public Library include holdings for many Chicago community areas and ethnic groups.
The city is partitioned into four main sections: Downtown (containing the Loop), the North Side, the South Side, and the West Side.
- Far North side: Rogers Park . West Ridge . Uptown . Lincoln Square . Edison Park . Norwood Park . Jefferson Park . Forest Glen . North Park . Albany Park . O'Hare . Edgewater
- North side: North Center . Lakeview . Lincoln Park . Avondale . Logan Square
- Northwest side: Portage Park . Irving Park . Dunning . Montclare . Belmont Cragin . Hermosa
- Central, Near North, and Near South side: Near North Side . The Loop . Near South Side
- West and Near West side: Humboldt Park . West Town . Austin . West Garfield Park . East Garfield Park . Near West Side . North Lawndale . South Lawndale . Lower West Side
- Southwest side: Garfield Ridge . Archer Heights . Brighton Park . McKinley Park . New City . West Elsdon . Gage Park . Clearing . West Lawn . Chicago Lawn . West Englewood . Englewood
- South side: Armour Square . Douglas . Oakland . Fuller Park . Grand Boulevard . Kenwood . Washington Park . Hyde Park . Woodlawn . South Shore . Bridgeport . Greater Grand Crossing
- Far Southwest side: Ashburn . Auburn Gresham . Beverly . Washington Heights . Mount Greenwood . Morgan Park
- Far Southeast side: Chatham . Avalon Park . South Chicago . Burnside . Calumet Heights . Roseland . Pullman . South Deering . East Side . West Pullman . Riverdale . Hegewisch
Street Numbering System
Before 1909, the river was the north-south dividing line. In 1909, the city was divided into four sections. 
Prior to 1909
Prior to 1909, the river was the north-south dividing line for streets which crossed it. North Clark Street would be that part of the street north of the river. On the west side, Randolph Street was the dividing line as far as Union Park (whose western boundary was Ashland). Beyond that, Lake Street was the dividing line. The Chicago River divided the city into three parts. North Division was from the North Branch east to the Lake; South Division was from the South Branch east to the Lake, and West Division was everything west of the river's branches. In 1879, the South Division adopted the even-odd numbering system in present use.
1909 - present
In 1909, the city was divided into four sections with the corner of State and Madison as the dividing point. Madison, running east and west, divides streets running north and south. State Street, running north and south, divides streets running east and west. One hundred numbers equal a full block and eight hundred numbers equal a mile. So 800 N. State would be one mile north of Madison. 800 W. Madison would be one mile west of State. Streets that run at an angle may be numbered either way.
All numbered streets such as 18th, 31st, etc., are on the south side. 600 E. 40th St. is six full blocks or 3/4 of a mile east of State and 40 full blocks, or five miles, south of Madison. Chicago has a small east side, mostly south, because of the angle of Lake Michigan. The term "East Side" refers to the area on the far southeast side near Indiana.
- In a street address, even numbers are on the west and north sides of a street; odd numbers are on the south and east sides. 817 W. 18th St. is on the south side of 18th, which is 18 blocks south of Madison (2-1/4 miles) and 8 blocks (one mile) west of State.
- Not every block shown on the map is a full block numerically. For example, Madison Street from State to Dearborn is only a half a block numerically. Dearborn is 50 west. Clark Street, the street after Dearborn, is 100 West. (Numbers may extend to 100 but most street numbers go up to 60 or so)."
- A Look at Chicago has ward and enumeration districts (ED) maps for Cook County for the 1870 through 1930 censuses. It also has ward descriptions.

Gazetteers of Places/Localities
Land and Property
Many genealogy books describe how to find land records for rural America. For ancestors who lived in a city like Chicago, though, a very different set of resources is available. A number of online databases give information about historic residences in Chicago and Cook County. Armed with an address from a census, you may be able to flesh out details about an ancestor's life and get a glimpse of where they lived.
It is possible that your ancestors were responsible for the construction of the building that they lived or worked in. The Chicago Historical Society has an index to building permits issued between 1898 and 1912. The index is searchable by original owner's name, historical street name, architect, and the contractor issue date.
The historical street name field in this search hints at the fact that Chicago streets have undergone several name changes over time. The Newberry Library has three excellent documents detailing the changes. Specifically, there are PDF files for the 1909 and 1911 street renumberings and a general index to old and new street names.
With a current address for a historical property, it is easy to find and see the current structure at a location, for example by using Google Maps street view . To find out if the current structure is where an ancestor lived, a helpful tool is the Cook County Assessor's search. It is available through their webpage:. The basic search requires an identifying PIN for the property; however, an advanced search provides a more convenient search by address. In this search, be as general as possible in the street name for best results (for example, enter 59 instead of 59th Street). In addition to a description of the property, the results of this search provide a recent picture and the structure's age. This page will tell you if the building you see today is the same one that an ancestor lived or worked in many years ago.
- Chicago Neighborhood Maps
"Discover the past by address." Search this site by entering the address of an ancestor. Addresses may be identified in a census, voter registration, or city directory. The search function then allows the marking of significant locations.
For example, search for the parish churches closest to the residence of a Catholic ancestor. Click on the hyperlink for each church to identify the Family History Library microfilm number of the baptismal and marriage records with the corresponding years. Films can then be ordered through a local Family History Center. ChicagoAncestors.org is sponsored by the Newberry Library.
