Hi Elmita, since they lived in Jackson Co. after the 1930 Census, info about their descendants is more difficult to find. (That's the most recent Census viewable by the public.)
I'd contact the Rogue Valley Gen. Soc., www.rvgslibrary.org/ or email@example.com. They do research for a reasonable rate. They might have cold copies of Polk Jackson Co. Directories, birth records, etc. Successful Hunting!
