If you’re alive today, then somebody in your genealogy obviously survived the black death... Otherwise, you wouldn’t be alive.

Or were never exposed to it.

If your ancestors are of European decent, that’s highly unlikely... If you’re of North American indigenous decent, or Australian indigenous decent you may have ancestors who avoided it... At some point, it likely existed in pretty much every other part of the known world.

Then again... Maybe you got a lucky (or unlucky) set of genes. I’d assume that you would likely be better of to have somebody in your genealogical past who actually survived it.
