My most unusual are Penninah (Biblical I believe and, according to a Googled link - Hebrew, meaning coral; pearl), Milliken, Orchard, Thaddeus, Lancelot, Damaris, Clementina, Kezia.
(Quite a tame bunch when compared to some of these others on this thread

)
Most males in my tree appear to be called William, irrespective of surname!
