Are you an O’Reilly or an O’Rourke? One of two famous Cavan families – there are many more!

The O’Reilly Clan were once the rulers of Breffni, the kingdom in which Cavan is located today. The O Rourke’s were their rivals. Both families fought and died over the Kingdom of Breffni – a land worth fighting for . Today, there are many O’ Reilly and O‘Rourke families still in County Cavan and across the world. Find out more about these famous families and all others at Cavan Genealogical Research Centre, based in the Johnston Library & Farnham Centre, Farnham Street , Cavan. The centre offers a full genealogical research service for people with Cavan ancestry.
