I believe I have a line of this family in mine:

Katharina Klossner
b. 1 Jan 1792 in Erlenbach im Simmental, Bern, Switzerland
d. 26 Dec 1834 Erlenbach i. S., Bern, Switzerland

wife of
Johannes Blum
b. abt 1793 also Erlenbach im Simmental, Bern, Switzerland

I believe Katharina was a daughter of:

Jacob Klossner
b 1760 in Demitigen, Bern, Switzerland

and his wife:
Susanna Wandfluh
b. 1763 in Frutigen, Bern, Switzerland

The Klossner line tentatively continues back to
Peter (b 1737) father of Jacob....

and though another branch of this family:
Magdalena Klossner, daughter of Christian, son of Christian, son of Hans, son of Peter (b 1573) all of Diemtigen but again this is tentative....

let me know if you'd like more info-

thanks
