Gaelic Origin · Root meaning ‘wise-headed warrior’
Concannon comes from Ó Concheanainn, joining cú (‘hound’, in the old sense of ‘warrior’) with ceann (‘head’) and a term for wisdom — read together as something like ‘wise-headed warrior’. The family were established in County Galway.
Another entry in Gaelic Ireland's long habit of naming its warriors after hounds — brave, but never mindless with it.
Irish form: Ó Concheanainn
