It seems there are lots of cases across the board where "women adopt traditionally male thing" has become the norm in this timeframe but not many where "men adopt traditionally female thing" at quite the same rate or scale.
That is the pattern. Rarely would you have a baby boy using a women's name. Broadly speaking there is a general stigma within society going the other direction then women adopting male things.
A baby does not "adopt" their name, though. It is given to them.
I think there's something to this, but also you've got to think about the cultural standards where "female" is considered "abnormal".
e.g. you have "toys" and "girl toys". "clothes" and "girl clothes" and such. It's not everywhere or everything but there is a trend.
