Hello,
My mom has a box of semi-vintage (1940's-1950's) letters.
A family friend my mom (and sibs) affectionately called "Aunt Mamie KNABLE" makes an appearance in the letters.
I think in an album there may even be some type of greeting card and/or a funeral card regarding Mamie or another KNABLE family member.
"Aunt" Mamie KNABLE is a part of mom's memories of childhood. A fond reminiscence.
