Tomahittan?

>I'd have thought that the -y- in Monyton went with the Moni- part?

It goes with both parts actually.  maNniN + ithaN.

I've discussed Tomahitan with Ives and neither of us has an etymology for it.  The H is in the way of considering it Siouan "Big Town".  Toma also passes for Choctaw 'town', but hitan doesn't ring any Muskogean bells with me.  Nobody really knows who these folks were.
