We are the McDonough County Genealogical Society located in Macomb, Illinois.  We meet the 3rd Monday of each month at 7:00pm at the Western Illinois Museum.  We have a program of genealogy interest before our business meeting.  The public is always welcome.  Check our event calendar for specifics.

Our Center is open 3 days a week — Tuesday afternoon, Friday all day, and Saturday morning.  Our center is staffed with volunteers who will gladly help you learn more about your ancestors and how to document their lives.

Check our announcements page for the latest news and updates.

Does your employer offer a matching gifts program?  Many companies offer such programs to encourage employees to contribute to charitable organizations. Some provide matching funds to support employee volunteer hours. Most of these programs match contributions dollar for dollar, and some will even double or triple the amount of your gift!  Please check with your company to see if it offers a matching gift program that will match your gift or volunteer hours to the McDonough County Genealogical Society.
