Gondor or Arnor?

That's an important point, as I forgot about the existing communities that had already been established before the Downfall. Most of the Faithful did indeed have Pelargir as their chief destination.

As noted above, Elendil had four ships, Isildur three, and Anárion two.
If we're splitting 'heirs' though (), we aren't told how large the ships were, nor the numbers on board.
