Heavener, Oklahoma Grade School

Here is a picture, Ruth Doyle, had in her box of photos. I don't know for sure which school it is or any of the persons in the picture. I think that the girl on the top row, fourth from the right is Catherine Harris, a cousin, and the boy in the overalls in the second row is Eugene Cox, another cousin. Can anyone identify the school or anyone in the picture. They went to Independence School, but this may be a school in Heavener.
