How Many Babies Were Named After John Travolta?

We’ve been watching John Travolta for decades. He’s played a Sweathog, a bubble boy, a hit-man, a chubby 1960s housewife…

Despite all this output, though, his surname has appeared on the SSA’s baby name list only once:

• 1978 – 11 baby boys named Travolta

Were the parents of these babies inspired by Travolta’s portrayal of disco dancer Tony Manero in Saturday Night Fever (released in late 1977), or by his role as Rydell High greaser Danny Zuko in Grease (released in mid-1978)?

My money’s on Saturday Night Fever, but both films did extremely well at the box office, so it’s hard to know for sure.
