I will send the photos to you if you like, if you will please let me know your email address. I have discovered that the young boy in both of the photos is named Charles (in addition to the other Charles, the dwarf). He was the son of an Ella and John Decker (I was mistaken about the sister's name being Ella). I doubt they are your relatives anyway, but who knows? The children's photos were taken in PA.
After a little searching, I discovered that I had originally found some of the Decker photos on Ancient Faces, and you can find them there by typing "Decker" into the search engine. If you aren't able to find them, please let me know and I'll send them to you.
I copied and pasted the link below, hopefully this will work:
