Bert, I would email you directly but I don't know how to find your email address from this message.
My most recent Ljunstrom ancestor Christina Marie, was born in Wemmerly Kalmar Sweden in 1861 and came to America in 1883. She settled in DeKalb County IL. She married John Axel Nelson who was born in Sadravi Kalmar Sweden, and they eventually brought both of their families to America. Christine's father's name was Swan and her mother was Christina (surname unknown). I would like to know more about this family.
