It's a pleasure to meet you as well--and truly, no apologies need be given. I understand entirely too well how this circumstance can cause one to forget such matters.

Your duke is unknown to me, I'm afraid. Either he is recently arrived and I have yet to meet him, or he is not here yet. I can't guarantee that such will happen, either, though it's entirely possible.
