The Mequon Thiensville Historical Society (MTHS) was founded in 1987 under the leadership of Don and Bev Silldorff with the initial support of the Mequon Men’s Club. Since its inception, the Society has depended on the community for support. We receive no government funding. The MTHS depends entirely on people like you for volunteers, funds, donations of historic photos and documents, and members.


One person can’t do everything to support the Society, but each of us can do something.

Please start by joining MTHS. For as little at $15, you can become a valued member of the Society and receive our quarterly newsletter. As you go through things in your home, please keep the Society in mind as a possible new home for your pictures, family histories, or other items related to the history of our community. If you would like to become actively involved in the work of the Society, consider becoming a volunteer in our archives, working on one of our committees, or joining our board of directors.
