I have written several times recently (http://www.google.com/cse?cx=003715150024579880844%3Aulyzue1ivzu&ie=UTF-8&q=+Burr+Oak&sa=Search) about the tragedy of the Burr Oak Cemetery near Alsip, Illinois. The news services have also been full of stories about the cemetery. As many as 300 graves at Burr Oak Cemetery near Alsip may have been dug up and the remains dumped so the plots could be resold. To help families search for their loved ones' graves, the Cook County Sheriff's office is building a database so families can search for images of headstones. The new database is sponsored by Chicago Tribune and the information has been entered by police officers, mostly those from the Cook County Sheriff's department.
The new online site allows you to search the sheriff's database by name, and browse by decade and year. The site presently contains photographs of over 9,500 headstones of those interred in the cemetery, which are all available to view online. The sheriff's office created the database and will continue to update with additional photos of the nearly 100,000 graves at the cemetery.
From the homepage, you can either search for a specific surname, or browse the stones by decade of death. Keep in mind that the data was entered by police officers, not by trained genealogists. The officers are perhaps not as careful with surname spelling as you and I might be. You might want to become a bit creative when searching for names, especially for those that might have unusual spellings.
