Entwives going West?

[Keeper of Dol Guldur]

You know, it seems like a ludicrously simple, easy, basic question. But none of us has any idea. Tolkien imagined maybe they'd been wiped out in their gardens near Dagorlad, and in the brown lands. Some could have been taken as slaves (there is a theory that is where the Olog-Hai came from), and farmed the bleak fields near Rhun. A lot of people theorize that the creature cousin Hal saw on the north-marches, which was tall as an elm (and from the conversation looked like one too), was an Ent, but it could have been a troll or giant as well. Remember that fleeing west did not necessarily entail going to Valinor, the forests and hills around the Blue Mountains were fairly safe places to be. I actually assume that the thing seen was an Ent, not an Entwife, who may have wandered from the forests at the south-western Misty Mountains to Rivendell, and then passed west through Rhudaur and onward because of Saruman, or Dunlenders, or something of the like. Maybe even it fled because of the return of the shadow, or the demon of Moria. I don't really know if it was an Entwife or not, nor what finally happened to them though. But I do love a good enigma.
