Name Changes?

[Arvegil145]

Shouldn't Sador be changed to Sadog, as per 'Of Dwarves and Men' (c. 1969) from The Peoples of Middle-earth, p. 309? (Also, shouldn't he be a Druadan according to the same text?)

Additionally, there is strong evidence that the characters of 'Magor' and 'Hador' should switch places, in that Hador becomes the grandfather of Magor, and not the other way around as it has been presented in most writings. This is largely because Tolkien wanted Hador to become the Lord of Dor-lomin earlier than in the published Silmarillion. This information comes from 'Of the Kindreds and Houses of the Edain' from the 'later Quenta' - namely, from some of the later revisions to it, found in The War of the Jewels, pp. 225-6.

Here is a quote from 'The House of Hador' genealogy commentary by CT:

In hasty pencillings on Hador table II the note saying that Magor and Hathol served no Elf-lord but dwelt near the sources of Teiglin, and that Hador was the first lord of Dor-lómin, was struck out; while at the same time Hador Lorindol first lord of Dorlómin was written above Magor (the Sword), and Magor Dagorlind the Sword singer in battle above Hador Lorindol. This reversal has been seen already in emendations made to the carbon copy only of the text of the chapter (pp. 225-6, §§16, 31-2 - where my father changed Glorindol, not to Lorindol, but to Glorindal). That this was not an ephemeral change is seen from the Athrabeth, where Adanel is the sister of Hador Lorindol, not of Magor.

This note, I believe, dates from c. 1959/1960.
