We've just found out that the baby we're expecting in June will be DS2. For DS1 I couldn't pick from our shortlist so DH chose a quite common biblical name but we've agreed that this time I'll get the deciding vote. I love some of the more unusual Old Testament names such as Levi, Malachi, Ezekiel... My dad suggested recently that these names can only be carried off by someone who is either Jewish or black...
It had never occurred to me to not choose a name just because it might be more popular in another culture! 
Would anyone not choose a name they loved because someone somewhere might make assumptions about the child's heritage?! I'm really tempted to choose an even more unusual name, just to wind my dad up... How about little Habakkuk?
