I was just reading an essay on the Huffington post by a father of twin girls. Their names are...
Rose Austin
Evan Heart
(Again, they're both girls). WDYT? I think Rose Austin is pretty awesome. Evan--I despise it on a boy, but I like the sound enough on a girl. But then it reminds me of Evan Rachel Wood, and she seems kind of lame. Heart is lovely in the mn spot.
What I like most about this sibset is the balance of names. Both get a word name, but one is common and in the fn spot and one is uncommon and in the mn spot. And they both get one unisex name.
