Love, love, love. I am irrationally infatuated with
Boris.
My favorite combo is
Boris Koloman. It took me a long time to find a middle name that I felt did
Boris justice and at the same time didn't sound uber-Russian (since that's not what I'm personally going for with it).
I like it in the middle name spot with a few of my favorites but it seems like acknowledging
Boris as some kind of secret shame to make it the middle name. ;-) Otherwise I do like
Karl Boris and
Robert Boris (though I usually pair them together as
Karl Robert, so those aren't my stock
Boris combos).
