the difference is much more pronounced ...
On the girls' list than on the boys' list, with the notable exception of Ptolemy.
Solveig says she wouldn't even blink if she encountered a Ptolemy, but that is not the same thing as Ptolemy's popularity on the BTN list being related to its popularity in real life, and the fact is she is highly unlikely to ever encounter a Ptolemy of any age who was given that name by his parents (as opposed to giving it to himself as a stage name or something.) In fact, if she, or anybody else, said they encountered one, it would be a very big surprise. I would be fairly sure that anyone claiming to have known "several" Ptolemies is full of BS.
On the girls' list, only a couple of top-100 names are in the top 20, and top-tenners Isabella, Ava, Emily and Sophia are nowhere to be found.
