On November 15th, 2023, American Marriage Ministries had an article about cousin marriage:
A quick intro to marriage customs between cousins. Curious if you can marry your first or second cousin, how common this practice is in the US or around the world, or why some see it as controversial while others don’t? This short article looks at the history, culture, practice, and prevalence of cousin marriage – also known as consanguineous marriage.
Every month, thousands of people search online for information on the legality of first and second cousin marriages.
“Can you marry a second cousin?” they ask, or “Which states allow first cousin marriage?” and “Is marriage between cousins legal?” …You get the idea.
Of course, some of these queries come from simple curiosity. Some are likely made by snickering teenagers, looking to cause trouble among classmates, or from uninspired comedians and bored office workers. (We’ve all heard the jokes at least once, right?)
But many of these searches are probably made by individuals who, well, want to marry their cousin.
It makes us wonder: How common is marriage between cousins? Where is it legal to marry a cousin, and under what conditions or restrictions? Why is there so much controversy surrounding these types of consanguineous marriages (marriage between relatives), and has it always been this way?
Let’s take a look!
Terms to know: ‘First cousins’ are non-siblings that share grandparents, and ‘second cousins’ are non-siblings that share great-grandparents. Some people may also be cousins through marriage or adoption; different rules may apply to cousins who aren't related by blood.
