: Check out this link (below) to an archived thread about Gil-Galad and Orodreth. I think it's the one you´re looking for.

: Cheers Mjolnir

: : Everybody who seems to be well-read in Tolkien minutiae tells me that Tolkien's later writings made Gil-galad the son of Orodreth. Which book is this information in? I've read HoME11 and it has a LITTLE bit of info on the subject, but it is VERY inconclusive. I don't ask you to give me a detailed rework of the genealogies, just which book I should look for it in (though, if you really WANT to give me the genealogies, feel free :)
