Under Texas law if you have lived with someone for two or more years and you introduce that person as your wife you are by common law married. That just about covers everyone there. the statutory rape is going to be the biggiest issue. The argument is will the girls were married so it's ok. Not in Texas, parents can't even give concent to marrage to girls that young. They were putting all the girls in dangers by creating an environment that said it was ok for young girls to have sex. Its a cirlcle effect. In order to justify breaking one law they would break another.
