5 days late, but to answer your question incest isn't actually legal in
Alabama:
Incest.
(a) A person commits incest if he marries or engages in sexual intercourse with a person he knows to be, either legitimately or illegitimately:
(1) His ancestor or descendant by blood or adoption; or
(2) His brother or sister of the whole or half-blood or by adoption; or
(3) His stepchild or stepparent, while the marriage creating the relationship exists; or
(4) His aunt, uncle, nephew or niece of the whole or half-blood.
(b) A person shall not be convicted of incest or of an attempt to commit incest upon the uncorroborated testimony of the person with whom the offense is alleged to have been committed.
(c) Incest is a Class C felony.
Cousin incest might be, I would say you should ask a lawyer otherwise you could be risking jail time. Also incest is expressly illegal in all the US states
but two. Those would be Rhode island and New Jersey. I find that incest laws are like age of consent laws, in that people are very misinformed about them, and it's actually easy to get informed with a quick google search but people just never do that and just go with their intuition.
