From the album of my Grandmother, Della Luke Webb, that I received from my cousin, I have several group photos of school children. On one, "Clinton School" with my dad's name on it, he looks like he is about 5 years old, so it would be about 1915. On another he is about 12, and the third one has my aunt who was born in 1912 at about 8 years old (I think I know which one is my dad, but not sure!) From other photos I know that they also attended Caddo Mills school.
If anyone is interested in a copy of these photos, please email me and I will forward one on to you.
