re: Did you know. .....

Naming trends in English-speaking countries (over the last century or two) have followed a general pattern.

First it's a traditional Irish/Anglo surname
Becomes a boy's first name for few generations
Becomes a girl's name after a few generations

Madison
Blair
Cameron
Ashley
MacKenzie
Reese
Heather

There are hundreds of examples. New names go through the same pattern over generations. What it means is by the time we are older there will be girls named Connor and Jackson
