Second cousins dating wrong
A lot of my Monroe County relatives married first cousins.
Which is funny, you know, because even with all of our proscriptions against incest and such, if you read your Bible you’ll notice that humans started with just one man and one woman, so clearly their children would have had to hook up to propagate our millennia-crossing, evolutionarily dominating species, right?Cousin marriage is an important topic in anthropology and alliance theory.Children of first-cousin marriages may have an increased risk of genetic disorders, particularly if their parents both carry a harmful recessive mutation, but this can only be estimated empirically, and those estimates are likely to be specific to particular populations in specific environments.Anything at or above 0.0156, the coefficient for second cousins, is considered consanguineous; that includes relationships between people and their nephews and nieces. For one thing, 25 states ban marriage between first cousins, and another seven states have restrictions on it (for example, in Arizona first-cousin marriage is allowed only if both people are 65 or older, or if one is unable to reproduce).Those laws might make some individuals reluctant to say they are in a consanguineous relationship and result in some undercounting of relationships.In some countries outside that region, it is uncommon but still legal.
In others, it is seen as incestuous and is legally prohibited: it is banned in China and Taiwan, North Korea, South Korea, and in fewer than half of the United States.
If you do genealogy, and your ancestors were in the USA west of the Atlantic seaboard before the Civil War, odds are you'll find at least one set of first cousins marrying in your tree. There was a brief span of time in the US (1870 - 1930 or so), after doctors started washing their hands and before birth control was popular, when women routinely had 8 - 12 children, most of whom lived to adulthood.
If that happened two generations in a row, one couple could have 8 - 12 children who married and produced 8 - 12 children in turn, giving the original couple 64 - 144 grandchildren.
A number of people ask me that question after reading my page about cousins, which explains first cousins twice removed and second cousins once removed.
Short answer: sure, unless your family has a history of genetic problems.
After doing a little research, we are surprised to find that, in about half of the U. Of course, your question does not concern the legality of your prospective union, but what society will say.
