The specific rules for acquiring citizenship are very complex and fact specific. There really is no way of commenting on your eligibility for citizenship w/o a thorough review of your family history. There are many facts and dates that must be reviewed concerning your grandparents, parents etc.
If you are serious about investigating any citizenship options, you should consider consulting with an immigration attorney.
