Hi Connie! Found quite a lot on these folks. I suggest you check out the Family Search pilot program for the images of the Texas Death certificates (be sure and look at the actual images, as there can be frequent indexing errors). Also, I see by your email that you are in Texas (as am I.) Check with your library and you can get free access to Heritage Quest (which has the census images) through the Texshare databases.
In 1900 Roy is with his parents in Falls Co. His father is Edward and his mother is "Emelie". There are quite a lot of children: Roy is in the middle. If you can't get to an image or index of this, let me know and I will transcribe for you.
In 1920 Roy is with his wife, Susie, in Robertson Co. In 1930 Roy and Susie are back in Falls Co. Winston is listed. There are daughters and sons. Please note Wintson's younger brother Carter. I'll talk about that in a minute.
