Named for the Potawatomi word for the Yellow River, the Wythougan Valley Preservation Council initially formed in 1999 for the preservation of the Garn House in Plymouth, Indiana. Since that time the organization has continued to inform and involve the public on other projects for the preservation of local heritage. The Board of Directors is comprised of individuals from all ten townships in Marshall County and routinely evaluates potential projects in
communities throughout the county. As opportunities are presented for the preservation of community heirlooms, the Wythougan Valley Preservation Council is committed to protecting the enduring legacy of early Marshall County pioneers in forming and shaping today’s communities
With the celebration of its 15th year in 2014, the organization has completed several National Register nominations and rescued and restored the Garn House in Plymouth, Summit School in Tippecanoe Township, and Jacoby Church near Plymouth. In recognition of the State of Indiana’s bicentennial, the Council plans to have all National Register-eligible properties and districts in the county listed by 2016 and included in a publication telling the histories of each property.
The Wythougan Valley Preservation Council Fund was established at the Marshall County Community Foundation in 2010. This endowment fund is open to receive charitable gifts to assist with ongoing costs and future preservation work in Marshall County.
Wythougan is a member of the Marshall County Historical Society and an affiliate member of Indiana Landmarks.
