Thank you for the grave info! I had not thought of looking on find a grave. I have always wondered where they were buried. I have cross referenced the information in the thread about my great-grandmothers coming to America, but have not been able to pin-point who exactly Anna was yet. Thank you again for your input and suggestions!!!
Peter Lyngstad was married to Dorothea Hilden who's mother was a first cousin to my great grandmother. It would appear that if Anna Andreassen was Peter's sister we are only technically related by marriage. If I could find Peter Lyngstad's obituary then I could see who is listed as siblings. I should think by 1944 they would have that listed. Thank you again for your help! I know that Andrew and Anna had at least Three children - Elsa, Arthur, and Svanhild (spelling?).
