I haven't been able to track down a photo of Elizabeth (Finnestad) and Ole Andreas Knutson's daughter Edith (Ella) Olivia (Knutson) Ludwig yet, though I did come across this photo of Edith's daughter, Elizabeth Ludwig from the 1947 Rochelle High School (see red arrow) year book.
Elizabeth Ludwig was a sophomore in 1947. Elizabeth was the youngest daughter of Edith (Knutson) and Charles Edward Ludwig and the granddaughter of Elizabeth (Finnestad) and Ole Andreas Knutson. Her great grandparents were Mari and Ole Finnestad.
Sometime around 1949 or 1950, Elizabeth would marry Gerald Corson, who I believe lived in DeKalb, Illinois while Elizabeth was growing up in Rochelle.
