Hi Amy, Most of main researching is done in Jefferson, County, Oklahoma. Terral Okla. is where my family are from. I do the Terral cemerety. Good luck in finding your marriages records. Jefferson County, didn't start keeping marriages records till 1906 or 1908. If you are not 100% sure that they married in Terral Okla. Check Cooke County, Texas a lot of intermarried got married there or go to the Okla. Web site they have some marriages records on it. Let me know if I can help, I go to Waurika sometimes. Keep Hunting, Montana
