I'm not a Freels, but they are in my ancestry. You didn't indicate where in Okla. you or your Father were from, but a couple of my Mother's uncles went to Okla. (probably either Washita or Beckham Ctys.) from Texas and one group wound up in Calif. I guess they went to Okla. around 1915 or so. All of this line of Freels came from Tenn. to Texas around 1900. May be no connection with yours, but maybe worth a try. Thanks.
