Cadock is Welsh in Origin.

Cadock is a rare Anglicised form of the Brythonic/Welsh name Cadoc (Welsh Cadog, also Catwg), built on the Celtic root cad “battle, war,” with the -og suffix conveying “having the quality of” - hence “warlike” or “battle-hardy.” Breton usage preserves parallel spellings such as Kadoc and the shortened Cado, reflecting the name’s spread across the Celtic world.

The name is most closely associated with the 6th-century Welsh abbot and scholar Saint Cadoc (Catwg Ddoeth, “the Wise”), founder of the monastery at Llancarfan, whose cult led to dedications from Glamorgan to Cornwall and into Brittany (e.g., Cadoxton, Llangadog). Medieval hagiographies record Latinized forms, and English records show Cadoc, Caddoc, and Caddock. Contemporary variants include Cadog, Cadoc, Kadoc, Catwg, and Cado. Meaning centers on “battle” and a brave, steadfast character; Cadock offers a distinctive, heritage-rich choice for parents drawn to Welsh and Breton tradition.
