I found a few gems while looking through the photos from my Aunt Maxine's estate. It appears that a good deal of pictures of the family were in her possession. I scanned some negatives and pictures of the collection while I was visiting in Illinois.
To the left is a photo from the 1940's. I believe the child to be Leo Otis born in the early 40's. Grandma (Rudy Pearl Poundstone Clark) and Grandpa (Otis Elmer Clark).
This photo appears to be of the same time period. Wilma is on the left, then Leo Otis, and to the right David "Kent" Clark.
The family was enumerated in 1940 in Bear Creek, Christian County, Illinois.*
Leo Otis was born in Stonington, Christian County, Illinois just a few years after the enumeration. It does appear that the family stayed in the same county for a number of years.
I will be posting more finds as time permits.
