I have located the Marriage entry for Christen Jepersen and Maren Mikkelsdatter at Thisted, Hundborg, Thisted 1854-1869 Thisted, Hundborg, Thisted img 429 pg 491-#25a
https://www.familysearch.org/ark:/61903/3:1:3QSQ-G94H-X9X1-6?i=428&cc=2078555&personaUrl=%2Fark%3A%2F61903%2F1%3A1%3AQG8J-C1G9

My attempt is as follows:

Year: 1857

Groom: Ungkarl og Tømmer Christen Jepersen af Thisted, født d 5 Mai 1829 og Vacc 22 Juli 1830 28 Aar gammel

Location: I Kirken

Where I am having difficulty is where I have BOLDEN above. Any help would be appreciated.
