Can a moderator merge this entire thread with http://forum.barrowdowns.com/showthread.php?t=19550 ('Tolkien's final First Age timeline')?

Obviously I am working on this. :D Here is the link to view the current version, though only the first tab ("Options") is currently interactive. I don't know whether, as a viewer, you'll be able to use the drop-downs and have the list of milestones update; let me know?

This... might actually resolve the heirs of Finwe? Using the 'latest assumptions' answer to each question, I get the Aman years as about 6500. Per per XVII.3(1), the average age of marriage is 36, ie 1800 SY. Per AAm, the first child comes after about 200 SY, and then more maybe at 200 SY intervals. If we do a Tolkien and use all of that directly, we get a timeline that almost works:

0: Finwe arrives in Aman
200: Feanor born.
400: Findis born.
600: Fingolfin born.
800: Lalwen born.
1000: Finarfin born.
2200: Maedhros born.
2400: Maglor born.
2600: Celegorm, Fingon born.
2800: Caranthir, Turgon born.
3000: Curufin, Aredhel, Finrod born.
3200: Amrod & Amras, Argon, Angrod born.
3400: Aegnor born.
3600: Galadriel born.
4800: Idril born.
5000: Celebrimbor born.
5200: Orodreth born.
5500: Melkor unchained.
6500: Death of the Trees.

The youngest generation are all adults, but not of marriagable age. If Fingolfin marries or has kids later than normal, we could sync Turgon and Finrod's births back up. To give Aredhel and Galadriel the same birth year will always require a huge gap in Fingolfin's children, but we've already established he's being a bit weird about things.

Galadriel remains far older than Tolkien wanted her to be, though: she's 43 life-years at the Return, which is somewhere late-thirties "mortal equivalent". Tolkien wanted her to be 20 growth-years, = 60 SY. Still, that's the only major hole in this version.

There's now a second tab, "Interactive Timeline", which shows everything I've integrated so far. Currently it has no way to rearrange rows or do any sort of error checking, so there's at least one option that breaks hilariously. I will try to integrate more of the points we've got different approaches to.
