Cavan Family History
Cavan Surname Meaning
Irish (Down): Anglicized form of Gaelic Ó Caomháin ‘son of Caomhán (Kevin)’ a diminutive of the personal name Caomh (see O'Keefe). In some cases, the name may perhaps be an alternative Anglicized form of Caomhánach (see Kavanagh).
Filipino: variant of Caban.
Vietnamese: apparently from a combination of two personal names (the middle name Cả meaning ‘the eldest’ and the personal name Văn meaning ‘literature’) recorded as a surname after immigration of its bearers to the US.
