What does your Surname literally mean?
According to ancestry.com, there are 2 possibilities.
1. (German) A person who lived "on the Ach" (river). The -er suffix in the name denotes an inhabitant.
2. (Swiss German) Topographic name denoting someone who lived "by the field".
I think the latter is most probable because my ancestry is mostly Swiss.
