I have a birth certificate for my grandfather Ernst Bachmann. He was born in Bern, Switzerland in 1903.
I doesn't have very much information on it. It has his father's name but not his mothers name. It has a female name on it Rosette born Bachman. I was originally guessing it is a sibling or maybe even a twin. But I've also been told by an aunt that Rosette was born Bachmann and also Married a Bachmann, so probably not a sibling.
I'm looking for a swiss census to help fill in the blanks.
Can someone direct me to the right place to search for this census?
It is a civil birth certificate with the seal of Bern on it
