I have an ancestor Claus Henry Rolfs, who was married to Sophia, and they had 2 children: Henry and Benjamin. They probably lived in the Elkhorn, Douglas County, Nebraska, area. Claus Henry Rolfs was usually called Henry Rolfs.
While surf the NET, I found a listing that showed that Henry Rolfs married Sophia Kaelber on November 21, 1880, at Douglas County, Nebraska.
Henry and Benjamin were born in 1885 and 1888, so there is a strong possibility that Sophia Kaelber did marry my Henry Rolfs. If you have any information about this branch of the Kaelber family, please contact me.
