First found in Switzerland. The name originated from the much honored position of the Landammann, who was the highest official of a Swiss canton (province). But as a surname it became prominent in Bavaria where it branched into many houses, many of which played important roles in tribal and national conflicts, as each group seeking power in an ever-changing territorial profile. The name can be primarily traced to an old noble family from the city of Augsburg; another branch possessed the castle Lauffenberg in the district of Altmuehl. A Bruno Ammann von der Lauffenberg is mentioned in chronicles as early as 1325.

Some of the first settlers of this family name or some of its variants were: Hans Uhlrig Amman, who settled in Philadelphia in 1735; John Amman settled in San Francisco, Cal. in 1850; Anna Ammann settled in Carolina in 1743; Jacob Ammann, age 24.
