Descendants of R.A. Edwards & Maggie Ward Edwards

A photo given to me by Robert Price, the son of one of the daughters of Gus and Maggie Edwards, I'm guessing that this was taken around Williamson, Bell, Burnet, Coryell Co area. I have no idea who these people are, but would be most interested in ANY help identifing them. Everyone I know connected with these families are deceased, but I'm sure there are descendants somewhere.
