Jayden, a variant of Jaden, is believed to be an invented name inspired by similar-sounding names like Brayden, Hayden and Ayden. Other theories suggest it's a unique and modern spelling of the Biblical name Jadon, which comes from the Hebrew name Yadon and is composed of the Hebrew elements yada, meaning "thankful," and din, meaning "he will judge." Jayden first appeared in the Social Security Administration's top 1,000 for boy names in 1994 and was already a top-100 boy's name by 2003. It spent several years in the top-10 and has now been a top-50 boy's name every year since 2006. It's the name of singer Britney Spears' son, Jayden James, whom she shares with ex-husband Kevin Federline.
