Actually, it was due to Tristan Ludlow (played by Brad Pitt) from the movie
Legends of the Fall (

But I wonder if the movie also caused Tristan to boost in popularity in France, the Netherlands, Scandinavia and Slovenia. It's also got some usage in Georgia (the country)! Here in Spain there are 2,278 bearers of the name (as Tristán) and what is surprising is the average age: 12.6 years, making it a relatively modern name.
