Could there be another Clifford Otto Dewing? Records I recently received say that Julius Dewing was married to Martha Hibler, not Underwood. And if Clifford was your great-grandfather, that would make you the daughter of one of Clifford's sons, who are enumerated under my uncle Lloyd's post (Hi uncle Lloyd!!) I knew all of my uncle's children's names but haven't heard your name. Seems odd, but maybe there are two Clifford Otto Dewings.
