I correspond with a gentleman in Germany who is researching this name. He speaks no English so we work through a translation program which is a bit difficult. If anyone out there has a connection with the Longschwager or Langschwager name, please contact me. There was a Katherine Longschwager Dietz in Maquoketa, she went to school with my mother in the 1930's. Thank you for any assistance! Ingrid Ruddy [email protected]
