<3 Lovecraft, Poe and Gaiman! Hmm, I think Hatter may appreciate his just-as-hot-as-his-wife-ness from afar, since he would like to not be broken. And you know he would prefer not to be caught by the Spades doing whatever happens to come to mind against the Queen's lands >_>
He would likely know Darian Dymond, though. Darian was just barely of age when the Chess war started and he fought in it (his mother getting him a cushy officer position, but him generally trying to get into the fights alongside his men). But since he has been disowned he hasn't been around Spades much outside of his pub. But they could still have known each other.
