What is the closest cousin you can marry?

Answered by Jeremy Urbaniak

The closest cousin you can legally marry in the United States is your first cousin. However, it’s important to note that the laws regarding cousin marriage vary from state to state. In about half of the American states, marriage between first cousins is allowed, while the other half has restrictions or outright bans on such unions.

Growing up, I never really thought about cousin marriage or its legality. It wasn’t until I became curious about the topic that I realized the laws surrounding it were quite diverse. In some states, like California and New York, first cousins are free to marry without any legal obstacles. On the other hand, states such as Texas and Florida have stricter regulations, allowing cousin marriage only if one of the cousins is infertile or over a certain age.

The reasons behind these varying laws can be traced back to cultural, social, and even genetic concerns. Opponents of cousin marriage argue that it increases the risk of genetic disorders in offspring, as cousins are more likely to share a higher percentage of their genetic material compared to unrelated individuals. However, it’s worth noting that the increased risk is relatively small, especially when considering that many people carry genetic variants without any detrimental effects.

On the other hand, proponents of cousin marriage argue that it is a matter of personal choice and individual rights. They believe that adults should have the freedom to decide whom they want to marry, regardless of familial relationships. Additionally, they argue that cousin marriage has been a common practice throughout history and across cultures, often serving as a means to maintain family ties, wealth, or social status.

In my own family, I have witnessed cousin marriages that have been successful and loving. These couples have built strong relationships and have raised healthy and happy children. While it’s true that there may be an increased risk of certain genetic conditions, it is important to remember that many other factors, such as lifestyle and environmental influences, also play a significant role in the health of offspring.

The legality of cousin marriage in the United States varies depending on the state. While second cousins are allowed to marry in every state, first cousin marriage is legal in about half of the states, with the remaining states having restrictions or bans in place. The debate surrounding cousin marriage involves considerations of genetics, personal choice, and cultural norms. Ultimately, it is up to individuals to make informed decisions about their relationships and marriage, taking into account their own circumstances and beliefs.
