We are the McDonough County Genealogical Society located in Macomb, Illinois.  We meet the 3rd Monday of each month at 6:00 pm at 201 South Lafayette (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 assist you in your research.

The Library WILL BE CLOSED  except by appointment.  Appointment times will be limited and must be requested several days prior to the day you’d like to use the facility in order to schedule workers.   

To schedule an appointment, please call our phone number at 309/255-5161, indicate the day and time you would like to make an appointment and leave an email address or return phone number for us to confirm the time.    MASKS will be required while using the facility.
