Brock Lesnar isn’t a southerner, he’s from the upper Midwest, and grew up in South Dakota and Minnesota, where a TON of German/Norwegian/Swedish immigrants settled. Because of that, and the fact that his surname sounds something like “Ragnar”, I figured he must be Germanic. However, according to forebears.io, there are people with the name “Lesner” living in Poland, Czech Republic, Russia, Ukraine and Belarus, and “Leznar” in Czech Republic, Poland and Russia as well. This all makes sense, as the American Midwest also has plenty of people who descend from Poles, Czechs, Slovaks, etc.
