Here is an explanation of our band's name, which is also the etymology of Prout. This is taken directly from a publication by Heraldry Names Ltd. Ballina Ireland.
The Irish sept O Diomasaigh, who had their seat at Clanmalier, on the borders of Counties Laois and Offaly, provide the origin of the Dempseys of today.
The name has its origin in Diomasach, which means "Proud" and the name was occasionally anglicised as Proudman. With the upheavel of the Old Gaelic Order and the Cromwellian wars, in the seventeenth century, they were stripped of their lands and power.
O'Dempsey, Chief of Offaly, was one of the few Irish leaders, who defeated Strongbow in battle, which he did in 1172, killing Strongbow's son-in-law in the process. In Penal times, the Dempseys were noted as priests. The greatest numbers of the name are to be found in Leinster, particularly Laois and Offaly. The name is, however, found widespread throughout Ireland.
