Under the statutes of some of the states the living together of the man and woman must be open and notorious.19 If a married man lives openly and notoriously with a married or unmarried woman, he is guilty of adultery.20 The statutes of Illinois and Georgia relating to this offense are substantially alike; that of the latter state is as follows: Any man and woman who shall live together in a state of adultery, or fornication, or adultery and fornication . . . shall be punished. Under this statute there are three kinds of indictable sexual intercourse, adultery, fornication, and adultery and fornication. Hence, if both parties to the criminal act are married, each is guilty of adultery; if both are single, each is guilty of fornication; if one is married and the other single, each is guilty of adultery and fornication.21 Therefore, under a joint indictment for a violation of such statute, one of the parties being married and the other single, the one cannot be convicted of adultery and the other fornication, but both, if guilty, must be convicted of adultery and fornication.
