Not sure but I believe that De Witt C and Nancy J Cooley MAY have been the parents of your Frona Cooley and that her siblings may have been Charles W and Elais M Cooley. I base that on the the previous message I sent which showed that Frona Cooley was a shoolmate of my grandmother Ruby (Barnes) Houston and the fact that De Witt C Cooley lived in the same location and county as Ruby's father JOSEPH T. BARNES and Ruby's husband's father WARREN BEAUREGARD HOUSTON (my great-grandfather) in the 1910 census for 1910 Census, for Oklahoma, Tulsa County, Owasso Township.
I can only guess that Frona was not include in the attached census page because she was already married to Mr. Wood.
