Name Changes?

[Findegil]

The note with Maedros and Maelor in Tolkien's Return of the King includes a reference to Umbarto being burned

I didn't observed that! But you are right it means we have an additional info on the timing. We have (not considering the the order of writing by JRR Tolkien):

- a) The Lay of Leithian Recommenced (certainly post-1955 probably much later): Both, Maglor and Maelor, used but finally settled on Maelor

- b) Late change to Later Quenta Silmarillion 2: Maglor changed to Maelor

- c) The Shibboleth of Feanor and notes on the names of Feanor's sons: Maedros, Maglor

- d) The Return of the King note: Maedros and Maelor

- e) The Maedron note (given in notes to TPOR): Maedron

From the names only I would orer these text d), c), a) & b) and last e). That is possible but does not ring true to me entirely. I rather think that Tolkien changed his mind (probaly more than once) about Maelor and returned in the end to Maglor. But then this is based on no fact.

And I want to stress again that the change Maedros to Maedron doesn't necessarily mean Amros must become Amron.

I agree to this. We can for sure use Maedron beside Amros. If we chose Maedron we might be forced to do so because I do not see an alternative for Amors that was given by Tolkien. Beside that, Maedron is not equivalent to Maedros in my oppioin as explained above.
