I am looking for the descendants of a Swedish family, Carl and Karen Hartwig, parents of at least two daughters, Eva and Elsa. They lived in south Minneapolis, MN, and when they bought a house in 1920 I believe Carl was about 50 years old. I now live in that house and have found a letter from Eva (I believe; the signature page is missing) written in about 1935 (the date is only given as "Saturday, March 26" and other clues lead me to believe it is 1935). I would like to return the letter to members of the family because it contains some wonderful details of their life. I have run into a brick wall trying to go forward from Carl and Karen. Carl died August 1941 and Karen, I believe, died in 1953. Their obituaries do not identify children, so I don't know what happened to them -- married names or where they lived. Can anyone help? Thanks!
Wendy
