Banning Cousin Marriages While there have been instances of the banning of marriage between cousins at various points through history, such as the Roman Catholics banning the practice for a time starting with the Council of Agde in 506 AD, for the most part marriage among cousins has been popular as long as people have been getting married.
In fact, it is estimated that as many as 80% of the marriages in human history have been between first or second cousins.
In fact, nearly a third of all people who claim they are in this type of relationship say these are college relationships.
Non-marital relationships are not the only ones in which long distance may be a factor.
Not only are they a pain to maintain, but they also tend to be destined for failure in the long run. There are many reasons why some relationships become long distance.
