: Was Imrahil an elf, or a mix like Elrond?

Imrahil was a Prince of Dol Amroth, chief settlement/stronghold/ cool-looking-place-on-the-sea-cliffs of Belfalas. He was a man, but some 1000 years ago, his homeland was the site of a haven used by Lorien elves. Amroth and Nimrodel were to rondevous there for the voyage, but that went ill for both of them, bad luck for them, good luck for Lorien songwriters needing subject matter.
Anyways, one of Nimrodel's handmaidens, I believe she was called Mithelas or Mitherelas or something like that, hitched up with the local lord, a guy named Imrazor the Numenorean (a name I've never seen explained since Numenor had sunk 2000 years previously and, thanks to Ar Pharazon's nasty ways, I'd figure Numenorean style names would have fallen out of fashion in Gondor).
Imrahil is a man with a touch of elvish blood, so the closest analog is Aragorn.
The line in the appendencies that trips folks up reads "There were three unions of the Eldar and the Edain..." not of Elves and Men. Mithrellas was sylvan or Sindarin, not quite at the Eldar level. Gondorians were descendants of Numenoreans who were descendants of the Edain, but nowhere do I see them calling themselves "Edain." They used "Dunedain," Men of the West aka Numenoreans, but hesitated to actually call themselves "Numenoreans," save for the strange case of Imrazor.
Hopefully, this makes sense.
