Cousins
My first cousin and Caroline are first cousins, once removed. My first cousin’s child and Caroline are second cousins. If Caroline and her second cousins someday have children, those children will be third cousins.
It was recently brought to my attention by a New Englander that keeping track of such things “is a southern thing.” My answer to that is, “No, it’s math.” It all has to do with the number of generations, or difference in generations, to a common progenitor.
There’s even a Wikipedia article about it with a great chart to help keep track, if you’re interested. What do you guys think? Is this a southern thing? Honestly, most southerners I know don’t keep track of it either. Maybe it’s just a weirdo Jon OCD thing.
