Thank you again, Lena!
This is my great grandmother on my mother's side: Edla Uhlin
When she was 40 years old, she gave birth to twins -- my grandmother and aunt, Karin and Ingeborg. She was not married at the time, and it appears that the father was the farmer she worked for.
Through the kindness of another genealogist, I now have information on Ingeborg's adoption by Edla's sister, Anna, as well as records for Edla's and Anna's siblings and parents. I do not have much information on my grandmother's (Karin's) adoption by the Bergströms or who they were and whether or not they had any other children.
I have never been able to find any other information about Edla and what happened to her after the twins were adopted. She just seemed to disappear. I would like to know if she ever left Sweden, or if she ever married.
I also know nothing about Erik Rosén, the farmer who fathered the twins. I don't know if he was married and had other children.
Thank you, thank you for your offer to look!!!!
