Unisex names are welcome of course, I just don't want to accidentally give the boys overtly girlish names. I have enough trials in store for them without hanging that on them too.
Sakon and Ukon came to mind at first but I always think of crime-solving puppeteers, or ninjas, when I hear those names. ^^;
I've tried finding a pair of names using name lists, but the lists I have for male names are generally shorter than for female names and often don't have meanings listed. It's been a bit like flipping through a dictionary for words that sound similar and then hoping the definitions are equal and opposite.
