The name Julian comes from the Roman names Iulianus and Julius, which are believed to be derived from the Greek word ioulos, meaning "downy-bearded" or "youth," though some theories suggest it's related to the Roman god Jupiter. It was a top-400 boy's name throughout much of the 1900s before finally cracking the top-150 for the first time in 1989. Julian has now been a top-100 boy's name every year since 2000 and a top-50 boy's name every year since 2013. Several celebrities have joined in on naming their son Julian, including singer Robin Thicke and actress Paula Patton, "The Fast and the Furious" actress Jordana Brewster, "Lone Star" actor Mark Deklin and "Friends" alum Lisa Kudrow.
