Where did you hear she must be 21 to marry in TN? You do need proof of SSN (card or license with SSN on it). If she is not a US citizen and has no SSN she would need a valid Passport and US visa or resident alien card. I see no requirement for parental approval if both parties are 18 or over. You also need proof of date of birth (birth certificate or gov issued ID with DOB). Call your county clerk and ask.
As for IL law, if you still believe you need the answer you should repost this question and list IL as your location so as to be viewed by IL attorneys.

Requirements for marriage differ from state to state and county to county. Most counties' probate courts or license bureaus have websites that explain exactly what the requirements are for marriage. I would check those out - whether TN or IL.
