In most of the Western world, while incest generally describes forbidden sexual relations within the family, the applicable definitions of family vary. Within the United States, marriage between first cousins is illegal in some states, but not in others. In twenty-four states marriages between first cousins are prohibited, and another seven permit them only under special circumstances. Utah, for example, permits first cousins to marry only if both spouses are over age 65, or at least 55 with evidence of sterility; North Carolina permits first cousins to marry unless they are "double first cousins" (cousins through more than one line); Maine permits first cousins to marry only upon presentation of a certificate of genetic counselling. The other states with some, but not absolute, limits on first-cousin marriage are Arizona, Illinois, Indiana, and Wisconsin.
First-cousin marriage without restriction is permitted in nineteen states — Alabama, Alaska, California, Colorado, Connecticut, Florida, Georgia, Hawaii, Maryland, Massachusetts, New Jersey, New Mexico, New York, Rhode Island, South Carolina, Tennessee, Vermont, and Virginia—and the District of Columbia.
First-cousin marriage is illegal in Arkansas, Delaware, Idaho, Iowa, Kansas, Kentucky, Louisiana, Michigan, Minnesota, Mississippi, Missouri, Montana, Nebraska, Nevada, New Hampshire, North Dakota, Ohio, Oklahoma, Oregon, Pennsylvania, South Dakota, Texas (such marriages may not be performed after 1 September 2005, although previous marriages are still recognized), Washington, West Virginia, and Wyoming, although the United States Constitution has been interpreted as requiring these states to give "full faith and credit" to such marriages performed in other states.[citation needed] Yet, in the absence of a United States Supreme Court ruling, the scope of the Full Faith and Credit Clause is not clear in this context, especially as it would have implications on whether states were required to recognize marriages commenced in Massachusetts between same-sex couples. There are conflicts and courts have interpreted the clause differently. Some states, such as Wisconsin [2], have marriage abroad laws that make marriages by their residents in jurisdictions in order to circumvent their state's marriage restrictions null and void, and marriages contracted in that state to avoid restrictions in another jurisdiction likewise void.
It's an offence to that child, because inbred children really are domb, it's no joke.
