History & Origin
The parent name Hayden is an English place- and surname from Old English heg, 'hay', and either dun, 'hill', or denu, 'valley'. As Hayden crossed to girls in the two-thousands, spellings multiplied; Hadyn shuffles the vowels for a sleeker look while keeping the sound.
It appears in American records from the early nineteen-nineties into the twenty-twenties, cresting in the late two-thousands. It reads as a modern respelling of the Hayden trend and remains uncommon.
