Just to add to the whole "house" and "noble" terminology debate, I figured I'd drop this here.
There was a quest in Ul'dah that indicated the use of the the term "house" in regards to a past wealthy family called House Skryvner. The term "lord" has also been used to describe many of the wealthy house leaders (like Lord Lolorito, Lord Skryvner, etc). You can view the full transcripts of the quest regarding House Skryvner here:

Some of the Ul'dahn Syndicate members have also been referred to as "nobles," such as in this FATE (that's right...Eolande from 1.0 is apparently dead ; ; ): http://ffxiv.gamerescape.com/wiki/A_Few_...f_a_Quiver
Additionally, there's also a hint of the term "house" being used in Gridania, though this is a bit more open to interpretation. There's a drop in a Gridanian dungeon that makes mention of House d'Arlendre: http://ffxiv.gamerescape.com/wiki/Heart_...27Arlendre
[[Knows entirely way too much about the upper class of Eorzea >.>]]
