This was somewhat tricky.

First step was to determine todays spelling of the bride's name: Curtt is not a spelling according to the Register of Swiss Surnames. When comparing with old spellings a change C <> K is quite common - also variations t / tt / th. So I checked the Register for names with just "urt" in the middle - an the result included Kurt and Kurth … with Kurth holding citizenship in Rütschelen (amongst other places). We also know that Joseph Leib Und Gut (Leibundgut), the groom, was from Rütschelen (easy to read),

The problem with the word in question is - it is overlapping with the G of "Gut" - to see a larger section, not just a small snippet helps here. Recommendation: always upload larger sections - see https://community.familysearch.org/de/discussion/comment/458272/#Comment_458272. The familysearch link is of limited usefulness - cannot be viewed from home - a nuisance for readers not knowing how to open these records on the Bern State Archive site. If one checks the entire page, one finds this word frequently: auch = as well. Combined with the info above, we therefore can be sure the bride was from Rütschelen as well.

BTW - I have adapted the title of your contribution to show todays spelling of the bride's name.
