Trub, Kanton Bern
I'm named after her, but not related to her. I believe that Muralt is the surname of "Truber" i.e. people from the Trub in the Emmental.
Her two sons and two daughters (none of them married) brought up my father, another boy and a girl
I seem to have heard the name Hirsbrunner in connection with the Trub too - hence this email.
