The "marriage paper" is meaningless.

Your wife's dad can prove his US citizenship with any of these documents; certified copy of his US birth certificate, certificate of citizenship, or US passport.

is your father a USCitizen, or no?

IF NO - be certain to write a letter of attestation, detailing that you assumed that he was, but in fact he's a LPR and that you made a mistake.
