I wonder how I can find out what happened to my grandfather's first wife and his daughter?
Per Ljungstrand lived in Biddeford 1889 - 1896. He worked in a shipping office. He was married to Johanna and they had a daughter.
Both his wife and daughter at the age of three died in a car accident.
What evidence have you found of your grandfather's residence in Biddeford? There is a weekly Biddeford newspaper from that period available here.
I found a photo of my grandfather from Biddeford. Yesterday evening I also found Biddeford weekly on the net just by chance. But thank you for your answer and now I will start research.
