Zwick & Jahn Funeral Home’s roots trace back to 1899, making it one of the oldest family-owned funeral homes in Indiana. On April 10, 1899 William H. Zwick bought an interest in the Auten & Gay Undertaking and Furniture Store in Decatur. William H. Zwick’s purchase began a thriving, family-owned tradition that has continued for more than 120 years and counting.
