What I have seen in the Diocese of Guadalajara, which is of course Catholic, if the couple the same number of generations from the common ancestor, the consanguinity would be described as 2nd degree or 3rd degree and the two would be full cousins. If one was two generations and the other three generations, the consanguinity would be 2nd with 3rd degree, or 3rd with 4th degree. The relationship would be 1st cousins once removed, or in the other case 2nd cousins once removed.
