I am looking for information regarding Anders Svensson and Kjersti Nilsdotter who where according to swedish church books married in the US November 7th 1887. They had a daugher, Maria Albertina, on August 27th 1890. They arrived back in Sweden again March 5th 1897. Anders' father Sven Larsson passed away during the time he lived in the US (March 1890) and in those records it is stated that Anders lived in Nebraska.
Kjersti's sister Anna Nilsdotter or Nilsson (born in 1873) also came to the US in 1893/94. I am guessing that she also came to the same place. I know that she never returned to sweden again. I would also like to look for further information about her. If she married, or had any children and what happended to her.
I have had some difficulties finding out which county they lived in. Which is the best place to look for further information? I know that searching for people in the 1890s is difficult. But any advise would be helpful.
