What do the names Adrian and Rory have in common? Both are boy's names that for a period of time had a feminine pop-culture influence (for Adrian it was Rocky, for Rory it was Gilmore Girls) but remained predominately masculine according to the statistics.
For some people of the generation that grew up when the Rocky movies were popular that made Adrian sound a bit feminine for a boy, but now that those doing the naming are mostly those that grew up after those movies came out Adrian is now comfortably masculine according to the SSA stats (and ranked higher last year for boys than it ever has before). Even during the Rocky years, the boys still had the majority with the name Adrian (for the most part even so when figuring in the sound-alike feminine form Adrienne).
A generation later another name that sounds feminine from a pop-culture influence to some but is still more common for boys is Rory. The TV show Gilmore Girls had a female character with the (nick)name Rory, and thus made the name more visible for a girl (although there were female Rorys previously such as Rory Kennedy and Pamela Redmond Satran's daughter). Although the aforementioned show made Rory crack into the top 1,000 for girls, it still ranks lower than it does for boys; now that Gilmore Girls is off the air it looks like barring another influential female Rory the name will come out ahead for boys in the long term.
