If the Charlotte Family means the same thing as the Donquixote Family, the "daughters" could mean something along the lines of division commanders. I mean, Whitebeard referred to Ace, Marco, and co as his sons. Big Mom could be doing the same thing. 35 division commanders sounds a lot more plausible than 35 biological daughters.
