Son of a---!

I blame Alison & Madison. Despite "son" written straight out, many -son names are now trendy on girls. And while most of course mean "son of ____", not all do, and I set out to find them.
So if you're looking for a unisex (or "unisex") name, here are some -son names that are neither patronymics nor overwhelmingly more common on boys, as well as some -san/sen/sin/sun sound-alikes.
