Likely a modern variant of Camden or Kenneth
Kenden is a contemporary American invention, likely created by blending the sounds of Camden (meaning 'enclosed valley') and Kenneth (meaning 'born of fire'). It follows the popular trend of two-syllable names ending in the 'en' sound. Because it is a modern creation, it lacks a singular historical etymology.
