Cemeteries

Burr Oak Cemetery 4400 W. 127th Street Alsip, IL 60803

Cook County Cemetery in Dunning Over 38,000 burials over seventy years, the cemetery served as an institutional cemetery for Cook County. The Cemetery database of known burials is a work in progress, with over 7800 entries.

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 Potter's Field. Among the number were approximately 4,000 Confederate soldiers who died at Camp Douglas who were buried in Potter's Field. Dis-interrments began as early as 1860, as families of lot owners re-interred 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 at Hidden Truths: The Chicago City Cemetery and Lincoln Park. A database of original Cemetery lot owners and a map are also available.

Graceland Cemetery 4001 North Clark Street Chicago, IL 60613-1992 Phone: 773-525-1105 Graceland Cemetery was established in 1860. Genealogy inquiries available via online form.

Land and Property Records
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 through the office of the Cook County Recorder of Deeds. See the Township and Sectional Map of Cook County for information about townships, subdivisions, and sections. 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. 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. 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. 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. There are a number of online databases that 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 ancestor was 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 the years of 1898-1912. 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 re-numberings 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.
