Here's something amusing. I had a hunch about the popularity of the name 'Logan' after the X-men movies were widely released and the character of Wolverine was introduced to a broader audience. I checked the
SSA database, and here's what I found.
The X-Men movie was released in 2000. The name 'Logan' ranked at 42 the year before, in 1999. In 2001, Logan ranked 29. Quite a respectable jump. And the name's popularity has continued to climb all the way to 19 in 2006. I can't prove that the movies had anything to do with Logan's popularity, but I strongly suspect they did. Logan has NEVER been that popular, usually hovering well below the hundred most popular names, and only beginning to climb in 1988, when it went from 144 to 109.
Jean, on the other hand, has actually declined in popularity since 2000. Even the delicious Famke Janssen couldn't inspire parents to revive Jean. It's peak seems to have been hovering in the 300s during the years of the two World Wars. It's too soon to tell if X3 gave Warren any new life (the SSA only lists data from 2006 and before, and any little Warrens named after Angel would've been born after the movie's premiere in summer 2006). It's another extremely old-fashioned name, peaking at 39 in 1920. Marie, Rogue's name from the movies, is mostly used as a middle name, and hasn't had much staying power on it's own since it cracked the top ten way back in the 1890s.
