re: #89 Targetpractice, Worst of Both Worlds
No way of telling, not without mandatory DNA testing. But one has to consider that there are several states in the union where marrying a first cousin is perfectly legal.
A first cousin is not incest, unless you’re the medieval church.
(Full disclosure: one of my sets of great-grands were first cousins. It was Belarus before the First World War. It snowed year-round, and they wouldn’t let Jews have horses. Or shovels. A first cousin was about as good as it got.)
