Marilyn Loehnig is an artist in German piano and button box accordion playing. She was a master artist in the Missouri Folk Arts Program's Traditional Arts Apprenticeship Program in 1996 and 1997.

Terryand Marilyn Loehnig have played old time and German music since they were 13 years old and both were members of Sonny Bottermullir’s Peace Valley Orchestra. While Terry served in the U.S. Army in Germany, the two decided to concentrate on German folk music. They formed the Loehnig Family Band in the early 1970s in which their three children played and sang. Son Erich, now 28, still occasionally plays drums with the band. They have played at many festivals in the Hermann area as well as the St. Louis Strossenfest, German Day in Omaha, and last summer they taped an appearance on the “Big Joe Polka Show,” which aired on RFD TV. The Loehnigs have recorded five albums. A retired rural mail carrier, Terry can divide his time and money more evenly between being a guitarist and being a farmer. Marilyn keeps house, but is often on hand to play for some of the many tour groups who visit historic and scenic Hermann. At our 1997 and 1998 festivals she performed with her button box apprentice Ehren Oncken, who has played with the band since. He currently juggles the musical engagements with his studies at the University of Missouri. Some of the songs and dance tunes traditional to the Missouri valley since the mid-1800s comes from Ehren’s great-great uncle, whom Marilyn knew in. when she was Ehren's age.
