you might try local history books and newspapers. some scots were shipped to this country by the ruling faction in great britain because they were unwanted, might have had jacobite leanings. some scots came here for the opportunity. you might have to look at passenger lists as you go backward in your family line.
don’t just look at surnames. there was a lot of intermarriage between the scots and the native americans.
i really can’t look much up, because cox is a common surname and most every family had an elizabeth/lizzie. choctaw scrip and chickasaw scrip were land grants given to the heads of family.
one of the roadblocks that you might be running into is the usual non-enumeration of females. wills, marriage license, death notice, cemetery records are sometimes all we can find of people. sometimes a christening record. sometimes a mention in a trading post log. sometimes a mention in a book. it is much easier to trace male relatives.
choctaw, and other native languages, were an oral tradition. they have no written records. choctaw only became a written language in the mid-1800’s.
it is unusual to trace native records back earlier than the 1820’s. there are native rolls and databases on accessgenealogy.com, the website with the dawes roll. look at databases and census records and the state where they were located. it is a very good resource. location is a very important suggestion for native affiliation.
the mississippi choctaw and chickasaw were given land grants in lieu of tribal membership. the head of house were given these 1830-1870. look in the land records. the authority gives you the information about whether they were given land because of tribal affiliation. for a quick and dirty, ancestry.com has these land records and they tell you the authority, but you have to look at the file “mississippi land records” “alabama land records” “louisiana land records”. you can print the deed for federal land records at the bureau of land records website.

at the search on that website, you want land patents.
they have a mapping feature (that is temporarily unavailable) and you can print the deed.
you should write to NARA http://www.nara.gov and give them the details of this record and get all the paperwork.
i can’t give you more details, as you didn’t include dates, locations, children or spouse. i can try to find them one generation at a time.
records are poorer in information as you go back in time.
