Mason, an English surname-turned-given-name, was originally an occupational name given to a stoneworker and was derived from the Old English word macian, meaning "to make." It started gaining popoularity in the late-1970s and debuted inside the top-200 for boy names in 1991, per to the Social Security Administration. Mason has now been a top-100 boy's name every year since 1997 and was a top-10 boy's name between 2011 and 2019 -- likely due to the birth of Kourtney Kardashian and Scott Disick's son Mason in 2009.
