Try looking at some names from either of your ethnic roots, maybe. I've found some that way that I really like and aren't too common.
Here's a few suggestions off the top of my head of names that I liked, but my DH wasn't wild about. Somebody should use 'em.

Girls:
Keziah (Bible name also, but uncommon - one of Job's daughters)
Talitha (Bible again - I think it's Aramaic for "little girl") BTW - I would pronounce it tah-LEETH-ah. You could also do TAH-lith-ah

Boys:
Jonas
Lane
Asher
Fraser
