Caydfan is Welsh in Origin.

Caydfan is a modern respelling of the Welsh name Cadfan, from cad ‘battle’ + fan, likely a soft-mutated form of man ‘place,’ giving the sense “place of battle” (also read as “battle peak”). The name is anchored in early Welsh history through Saint Cadfan, a 6th‑century founder of the monastery at Tywyn and patron of Bardsey Island, and by Cadfan ap Iago, king of Gwynedd in the early 7th century.

Rare in contemporary use, Caydfan adapts the traditional form to English orthography while keeping its Brythonic roots. Standard Welsh is Cadfan, pronounced roughly CAD-van; English pronunciations for Caydfan often follow KAYD-van. Variants include Kaydfan or Kaidfan. Related Welsh Cad- names are Cadfael, Cadog/Cadoc, and Cadogan. Possible short forms include Cade and Cady. The name is primarily masculine but could be used unisex in modern contexts.
