re: #104 SanFranciscoZionist

One set of my mother’s grandparents were first cousins. It was Belarus before the First World War, if you wanted to marry someone who wasn’t a cousin, you had to tunnel for miles through the snow.

Yeah, I suspect it did happen, and wasn’t a mistake in my research.
I’m completely unconcerned, I believe it was not uncommon at the time period in question.
