"The thing is mentioned" you say.
Mention 1 is saying "it's a leprechaun"
Mention 2 is saying it's the male counterpart to the banshee.
Here is a third mention I've found saying it's what people call
Manannán mac Lir
HERE IS ANOTHER Where its says there are TWO types, and one of them are demons
"who took on themselves human bodies of men or women, and by making love to the sons and daughters of men, and revealing to them delusive views of a glorious prospective immortality, seduced them into a fatal union by which they were forever lost from God." This one is special though. It is the first one in our entire data set, (4 points) to SOURCE IT.
All mentions which take the two Gaelic words for fairy (male), and of the mounds (is that right Mike?), cram them together and end up with so many different things.
NOT. A. THING. Yep, Doubling down here.
An anomaly in any give data set does NOT mean that the anomaly is "real" (in quotes because myth can only be so real).
There are literally more accounts of bigfoot
THIS YEAR than there is for your Far Shee.

I'm not deleting any of this, It's all glorious and I love it.
I don't think that was clear.
I presume this is your turn? I took this more as "the word is there it must be a thing". Not "I concede Banshee men aren't a thing, but maybe Fir Shee Far Shee Ben Shee Fear Sidhe Man Shee Banhee or W/E you want to call it is just a blanket term for a concept of fairy dudes"
