OH MY GOD I ACTUALLY HAVE A POSSIBLE ANSWER TO THIS

Groin seems to be a variant of a traditional Line of Durin name!!! Check out the family tree:

There’s been a King Oin and a King Gloin in the past. These names are tremendously repetitive and derivative, until you reach Borin. Then you have a bit of a departure in that branch of the family, and Fundin’s name seems to be derived in part from Farin’s.

Balin and Dwalin’s names also seem to be derived in part from Farin and Fundin.

But Groin’s seems to hark back to those old kings? Enough so that he is able to name his own sons after them, and they appear to be derivatives of his name, anyway.

So, there’s ONE possibility!

btw, this is totally disregarding Tolkien’s original source for many of these names, the Völuspá (the names Thorin, Thror, Thrain, Dain, Frar, Loni, Nar, Nain, Gloin, Dwalin, Balin, Bombur, Bifur, Bofur, Gandalf, Dori, Ori and Durin all came from this edda!)

I’m wondering tho: Some people have told me that the proper pronunciation of the -oin names sound more like O-win in the traditional writings, so if you take that into account, Fundin and Gro-win don’t sound as dissimilar.

Oh heck, yes – I forgot pronunciation! Totally agree!
