Kaiden

Kaiden is Caden's sibling in a K-leaning baby book, part of the great rhyming cohort of Aidens that reshuffled the American top 300 in the 2000s. Often traced, loosely, to a Welsh or Gaelic surname meaning "companion" or "spirit of battle," its modern life owes more to sound than etymology: the hard K snap, the soft "den" landing like a door clicking shut. Parents who chose it wanted something current, masculine, and easy to spell on the first try. Two syllables, one in about 1,004 boys, and unmistakably a child of its era.
