Within the ancient lands of north Munster and central Connacht provinces in Ireland - is found the ancestral history of the Family Sept now known as - Hannon - originally called by the irish surname - Ó hAnnáin.

We are an Irish Clann whose celtic tribal origins in the Emerald Isle date back to circa 500 BC. This was a time before surnames came into common use in Ireland.

We were part of the ruling Érainn tribal peoples of Ireland, who gave their name to the words - "Éire", "Erin" and "Ireland". From Co. Antrim south to Co. Cork, the Érainn tribes ruled the Emerald Isle long before the later Laginian (Tuatha dé Danaan) and Goidelic (Gaelic) Celts had arrived.

In time, our ancestors inter-married with the celtic Gaels - the tribal group who eventually came to rule all of the Emerald Isle. The Gaels had emigrated from Galicia, in NW Spain.

Heber, son of Milesius the Gael, had a descendent that ruled after him named Mugh Nuadhat - also known as Eoghan Mor who married a Galician princess named, Beara; who in turn gave birth to Munster's First King - Allioll Olum.

King Allioll Olum, married Sabia the daughter of the then reigning High King of Ireland - Conn Cétchathach (Conn of the Hundred Battles) of Connacht. Both King Alliol Olum and Queen Sabia helped give birth to...Cormac Cas. When King Alliol Olum died in 234 AD, Cormac Cas became King of Munster - and ruled till he died in the year 254 AD.

At the Battle of Clontarf held on Good Friday in 1014 AD, the Ó hAnnáin clan joined with their fellow Irish - lining up alongside the High King Brian Boru. Together the irish clans from Munster and Connacht provinces, fought and won the day - freeing Ireland from the invading Danish Vikings .
