Burr Oak Cemetery
4400 W. 127th Street Alsip, IL 60803 (773) 233-5676

Searchable burials database provides burial information, a map of the cemetery, and a photo of the headstone, if available. The cemetery filed for bankruptcy in 2009 following allegations of grave tampering and the re-selling of graves that resulted in numerous lawsuits. The Cook County Sheriff's Office maintains a web site with Burr Oak Cemetery Information, more than 50,000 headstone photos, and other cemetery information.

Chicago City Cemetery
City Cemetery existed as a burial ground from 1843 until about 1866, when further burials were legally prohibited. During that time, more than 20,000 were buried in the cemetery, which was subdivided into a Catholic Cemetery, a Jewish Cemetery, and a Potters Field. Among the number were approximately 4,000 Confederate soldiers who died at Camp Douglas who were buried in Potters Field.

Disinternments began as early as 1860, as families of lot owners reinterred their loved ones in newly opened Rosehill, Graceland or Calvary cemeteries. Following the Chicago Fire of 1871, a major effort began to vacate the cemetery.

The land was converted into a public park, now known as Lincoln Park. The Ira Couch family mausoleum still stands at the back of the park.

A well-researched account of the old City Cemetery is available on the website Hidden Truths: The Chicago City Cemetery and Lincoln Park. The website also include an online database of original Cemetery lot owners and a map.

Land and Property
Property research in Cook County is challenging and very time consuming. It is the reason one generally needs to exhaust every other type of record for Cook County before tackling the land research. The pre-1985 documents are available only at the Cook County Recorder of Deeds office.

Township and Sectional Map of Cook County

To do land research in Cook County, one needs to have the legal description of the property. It is possible to obtain a legal description if one has the "modern" address of the property. Link to the Legal Description Search Request page at the Cook County Recorder of Deeds' Website.

http://www.ccrd.info/CCRD/il031/help/LegalDescHelp.jsp

In Cook County there are two (2) types of conveyance (indexes) systems. One is a “regular” system that uses a geographic index instead of Grantor-Grantee indexes. The other is a Torrens or Registry System. Used for only a portion of properties in Cook County, those that had a clouded-title situation. It was a means of registering title to land with a financial guaranteed by a government unit that the title was “good”. A court action established the title and every subsequent transaction for the property had to be registered. Transactions for Torrens properties are either written in red in the tract books or there is a “T” after the grantee’s name. The Torrens systems was phased out a number of years ago.

With a legal description in hand, one needs to locate the property in the specific tract book. There are 1000+ tract books for Cook County. The tract books are ledgers. Each transaction for a particular parcel of land is recorded chronologically in the books.

Identifying the records in the tract books is the first step. The numbers recorded in the tract books are transaction numbers. To locate the deed one needs to find the transaction number in the deed books, another set of indexes. There is another set of numbers in the deed books (paging books). These are the numbers for the volume or book, the page, and the item of the recorded instrument (deed). One then orders the microfiche for the document.

It is very expensive to make copies of property records in Cook County. The first two (2) pages of each document are $10.00 and then $1.00 for each additional page.

Pre-Fire land records are privately held by a title-guaranty company. One must make an appointment to view the records. These too are organized by legal description.

Another “quirk” to be aware of is out-of-county property recordings.
