I don't know if any of your members would be interested, but I have a photograph of George and Kitty Landrum. It's been in my family since it was taken. They were the ancestors of the African American Landrum family in Texas.
They were slaves belonging to the Landrum family in Falls County originally. The photo belonged to my great grandfather Elmore (Pete) Landrum.
I would be glad to share it with others if there is any interest. I believe I already have a digital scan of it.
