Theories on the Identity of the Witch-King

How I came to such conclusion? By painstaking deductions and calculations that brought my faint suspicions that Tolkien tried to camuflage this fact, but nevertheless left some mileposts leading to it.

Don't you think, Olmer it deserves a separate thread? There is quite a fan-lore about the WK. I have read Isilmo theory, Tar-Minastir theory, at least two Unidentified Prince theories and even Tol-Elmar theory. I admit Ciriatan is new to me.

I have some ideas of my own. Here they are in short.
1. I believe that the WK's real name would be erased from the records for sure (as they have done later with the poor cat-lover Beruthiel who was only guilty of not being to her hasband's tastes).
2. I believe The WK was the one who commanded the Numenorean army sent to rescue Gil-Galad around SA 1700, so at least he was a prince of the royal house.
3. I believe the elves kept all the info about the rings secret from their human rescuers and allies.
4. I believe Sauron, being defeated, swore allegiance to Numenor and gave rich tribute and gifts to Numenoreans to stop them from attacking Mordor. One of the gifts would have been an elven ring to the Numenorean commander. So Sauron practically did the same trick he repeated later with Ar-Pharazon.
What do you think of it?
