If you are looking for information about the location in Sweden where your ancestors lived, see if you can find some professional photographs from Sweden. The photographer put advertising information along the sides and even on the back.
the clue to an approximate location within Sweden in this photo of my
farfar's mor in Sweden. The photographer's name and address were listed.
The town is listed as Wenersborg, the old spelling of Vänersborg. We knew
she had to live somewhere near there. She was born in Brålanda parish
and was married and lived and died in Frändefors parish, both of which are
fairly close to Vänersborg. Professional photos can be great clues.
This is the wedding photo of my farfar Johannes Olsson and farmor Signe Cecilia Elisabeth Ekman. They married in Storkyrko parish in the city of Stockholm in 1898. (She was born in Hedvig Eleonora parish in Stockholm city and he was born in Frändefors parish, near Vänersborg on the other side of Sweden, but his mother's sister lived in Stockholm and was the foster mother of Signe.) This is their wedding photo, with the photographer's information. If we hadn't already known where they married, this would have gotten us to the right area.
Although the locations often tell the approximate area where our ancestors lived, it is always possible the location is not where your ancestor lived. My farfar's sister (my great aunt) lived in Frändefors parish (near Vänersborg) but she must have been visiting her mother's sister in Stockholm because the following photo was taken there. It is possible that other relatives live near the location of the photo. The person had to be there for some reason.
The clues you need may be in old photos you or relatives have in your possession. Good luck!
