Cain is last of the Horadrim, and we know that he has done alot of traveling. He talks about not remembering Kurast so dark last he was there, and I think there are other references but I'm not sure. As for the Horadrim, all we really know is that it is a mage clan in the east, but it doesn't say all the members were eastern. It was formed by Tyrael, so it may have composed of others from other places, but the bulk was the three mage clans in the East.
