I know a few Rorys and they're all male. I am familiar with famous people like Rory McIlroy, Kinnear, Stuart, Bremner, McGrath...
(One of those is a friend of a friend of a friend, I don't know the others.)
A former boss's son was a Ruairi.
A friend's XP was Rory etc.
All male.
Anglicized form of Ruaidhrí. Typically a masculine name, it gained some popularity for girls in the United States after it was used on the television series Gilmore Girls (2000-2007), in this case as a nickname for Lorelai. Despite this, the name has grown more common for boys in America, especially after 2011, perhaps due to Northern Irish golfer Rory McIlroy (1989-).
Kelly, Ashley, Lindsay, Leslie, Courtney etc are unisex but would you want to be called any of those if you were a man?
Boys' names for girls aren't new. There are plenty of Danni, Nicky, Jo, Lindsay etc my age plus the odd Billie, Stevie, Micky, etc. I even know a Paule.
