James Wilson's Understanding of "Christian" and "Common Law" Marriages:

Here.

Disability to contract marriage may arise from immature age. A man, as we have seen before,q may consent to marriage at fourteen; a woman, at twelve years of age. If, before those respective ages, a marriage take place, either party may, at the age of consent, but not before or after that age, disagree, declare the marriage void, and marry again: but if, at the age of consent, they agree to continue together, there is no occasion for another marriage between them; that which has taken place being deemed a marriage, though only an inchoate and imperfect one. If, at the time of the inchoate marriage, one of the parties is, and the other is not of the age of consent, when the last arrives at that age, the first as well as the last may disagree; for in a contract of marriage, both or neither must be bound.r

In this day and age, saying a 14 year old boy and 12 year old girl are "marriageable," hence "sex-able" is termed "Pedophile Chic."
