Diarmaid Ó Seachnasaigh

Successive Ó Seachnasaigh's have ruled the district of Cenél Áeda na hEchtge since at least the 13th century.

The clan had been vassals of either the Ó Briain of Thomond or the Burke of Clanricarde, supremacy depending.

For over two hundred years Ireland west of the River Shannon had been beyond the pale of the Anglo-Irish administration based in Dublin.

From 1533, Henry VIII began integrating them into his realm, knighting Diarmaid Ó Seachnasaigh and representatives of other clans.

Ó Seachnasaigh's submission of 9 June 1543 stated that: All the manors, lordshipps, towns and town-lands of Gortynchegory, Dromneyll, Dellyncallan, Ballyhide, Monynean, Ardgossan, Ballyegyn, Kapparell, Clonehaghe, Tollenagan, Lycknegarishe, Crege, Karrynges, Tirrelagh, Rathvilledowne, Ardmylowan, one-third part of Droneskenan and Rath; the moiety of Flyngeston, Ardvillegoghe, Dromleballehue, Cowle, and Beke were now to be held by him and his male heirs to the crown.
