Show ContentsBrosnahan History, Family Crest & Coats of Arms

The ancient Brosnahan surname is derived from the Irish Gaelic "ó Brosnacháin," which may be derived from the place name Brosna in Kerry. 1

Early Origins of the Brosnahan family

The surname Brosnahan was first found in Kerry (Irish: Ciarraí) part of the former County Desmond (14th-17th centuries), located in Southwestern Ireland, in Munster province, where they held a family seat as Chiefs and kin to both the Dunns and the Dempseys. Irish history, after the Norman Conquest of England, was strongly influenced by the invasion of Strongbow in 1172, almost equal to the enormous Irish cultural impact on England Scotland, Wales and the whole of Europe before the Norman Conquest from the 1st to 7th centuries. Many Irish clanns, sept names were intermixed and family groupings became almost indistinguishable.
