Jayden is the only non-traditional name to have broken into the boys' Top 5, though now it has dropped down to Number 20. Jayden is a popular spelling of a very popular name that was given a big bounce after being chosen by Britney Spears. It first entered the Top 1000 in 1994, and its popularity soared to epidemic proportions through the late 1990s and into the 21st century, especially after the form Jaden was chosen by celebrity parents Will Smith and Jada Pinkett Smith.
Jayden's popular relatives include dozens of variations and rhyming cousins such as Brayden, Cayden, Braden, Kaden, ad infinitum, as well as the more legitimate Aidan/Aiden and Hayden. Jayden might also be seen as a descendant of such trendy names of the last generation as Jason and Jay.
Although there is a genuine Biblical personage named Jadon -- in the Old Testament, he helped rebuild the walls of Jerusalem -- this version of the name has a nouveau, invented feel.
The Jayden spelling is also used for girls.
