Children of more distantly related cousins have less risk of harmful genetic mutations.In fact, a study of Icelandic records indicated that marriages between third or fourth cousins (people with common great-great- or great-great-great-grandparents) may produce the most children and grandchildren.
Anthropologist Jack Goody said that cousin marriage was a typical pattern in Rome, based on the marriage of four children of Emperor Constantine to their first cousins and on writings by Plutarch and Livy indicating the proscription of cousin marriage in the early Republic.
Professors Brent Shaw and Richard Saller, however, counter in their more comprehensive treatment that cousin marriages were never habitual or preferred in the western empire: for example, in one set of six stemmata (genealogies) of Roman aristocrats in the two centuries after Octavian, out of 33 marriages, none was between first or second cousins.
When a question about cousin marriage was eventually considered in 1871 for the census, according to George Darwin, it was rejected on the grounds that the idle curiosity of philosophers was not to be satisfied.
Cousin and sibling marriage were legal in ancient Rome from the Second Punic War (218–201 BC), until it was banned by the Christian emperor Theodosius I in 381 in the West, and until after the death of Justinian (565) in the East, but the proportion of such marriages is not clear.
By the 1870s, Lewis Henry Morgan (1818–1881) was writing about "the advantages of marriages between unrelated persons" and the necessity of avoiding "the evils of consanguine marriage", avoidance of which would "increase the vigor of the stock".
To many, Morgan included, cousin marriage, and more specifically parallel-cousin marriage, was a remnant of a more primitive stage of human social organization. Briggs appointed a commission to study "idiots" in the state, and this study implicated cousin marriage as responsible for idiocy.Only Austria, Hungary, and Spain banned cousin marriage throughout the 19th century, with dispensations being available from the government in the last two countries.The 19th-century academic debate on cousin marriage developed differently in Europe and America.Though contemporaneous, the eugenics movement did not play much of a direct role in the bans.George Louis Arner in 1908 considered the ban a clumsy and ineffective method of eugenics, which he thought would eventually be replaced by more refined techniques. Since that time, Kentucky (1943), Maine (1985) [ETA: First cousin marriage is legal in Maine so long as the couple undergoes genetic counseling to ensure that – should the couple wish to have children - there is little-to-no risk of serious health defect], and Texas (2005) have also banned cousin marriage.Such marriages carried no social stigma in the late Republic and early Empire.Tags: Adult Dating, affair dating, sex dating
