In Greek mythology, Jason led a group of warriors called the Argonauts on a search to find the Golden Fleece. The name may also be a variation of Joshua, meaning the Lord is my salvation. Jason was a mega-popular name in the 1970s, thus all the middle-aged men named Jason today. It has waned in popularity since then, but has yet to fall out of the Top 100.
