It's worth also noting the truly terrifying journal of John Clyn who basically lived through, at least some part, of the height of the Black Death. https://en.m.wikipedia.org/wiki/John_Clyn
In Norway, the relatively common last name and place name Ødegaard translates to "abandoned farm" and while not necessarily exclusively caused by the black death it rose to prominence as people took on farms after it.
It's fascinating how visible it still is in naming so many centuries later. (In the UK people might be aware of an Arsenal player with that last name, for example)
Today, the place is called 'Kaldholen', which more or less translates into 'Cold dump'.
Worst thing is, we still live here, 700 years later.
But I live in London now and while there are things I miss about Norway, the winters are not among them.
30% (or rather, "something like a third"), not 60%.
I feel so fortunate to be alive in this time.
