Oklahoma Marriage Index RE: Rogers/Dillard

[LindaGravesT]

Is there an online Oklahoma marriages index? I need to find the marriage of my grandmother Mary Susan RODGERS or Susie Graves to Edward Lee DILLARD. They were married between 1910 and Sept. 11, 1918. Most likely it was 1913-1918. It might have been around Marietta, OK.
Thank you,
