The McLean County Genealogical Society
Since 1966, The McLean County Genealogical Society has provided assistance to thousands of folks interested in McLean County and the surrounding area.
We maintain a full service genealogical library in the McLean County Museum of History (200 N. Main St., Bloomington). Our library offers books and publications for research, computers affiliated with FamilySearch and Ancestry Library Edition, and usually a volunteer to assist you with your research.
Please check the History Museum website for available hours:
