Thx @Tam! Yes, some do look-a-like! Luckely DNA works different for the elfes. And if you have no other possible mates around then second-cousins or so, well rules change right? Now we don't even think about it, although it does happen from time to time, but in our early, prehistoric day I can imagine it happend too. Doesn't it still happen in some tribes and arranged marriages? And let's not forget about Recognition! That force doesn't consider for a bitt the fact that you might be family in some way.
