Next to the museum is an 1830's style log house. This log cabin was donated to the Union County Historical Society in 2006 by the Ellsworth Ohnsman family who at one time obtained and preserved a group of original log structures from Union County. The cabin was originally located on the farm of Edward Weller (1808-1889), just south of Marysville, who was a local clay tile manufacturer and potter. The cabin, with frame addition, has been restored to its original condition and is furnished, as it would have been in the early nineteenth century.

The Weller Log Home relocated to the Union County Historical Society in 2006 where its sits next to the Union County Historical Society Museum.		Frame addition to the Weller Log home, completely restored with a functional fire place and a second story loft.		In 1849, Edward Weller purchased land south of Marysville with a log home to raise his family and to build a successful clay pottery business.
