Maelan mac Cathmogha

Maelan appears to be one of the earliest recorded kings of the territory of Maigh Seola, later known as Uí Briúin Seóla. He is not recorded in the genealogies, of which Francis John Byrne has this to say:

The Uí Briúin pedigrees show every sign of falsification ... Uí Briúin Seóla of the Tuam area in County Galway ... trace their separate descent though lines of unrecorded or dubious ancestors to Brión or his suppositious son Dauí (Dauí Tenga Uma) in the 5th century; ... such an adoption guaranteed them the tribute-free status of sáer-thuatha and ensured that Uí Briúin power should stretch from the Shannon to Clew Bay.

Thus it would appear that Maelan, and by implication his possible descendants, the Muintir Murchada, were political allies and not blood-relatives of the Uí Briúin. Magh Seola was surrounded to the east by the Soghain and the Uí Maine; to the south Conmaicne Máenmaige and the Uí Fiachrach Aidhne; to the west by the Delbhna Tir Dha Locha; to the north and far north-west, the Conmhaícne.

In the first half of the 9th century, Ireland experienced raids by Vikings. Some occurred in Connacht:

• 812 - A slaughter of the heathens by the men of Umall (Clew Bay). A slaughter of the Conmhaícne by the heathens.
• 813 - The slaughter at Umall by the heathens in which fell Coscrach son of Flannabra and Dúnadach, king of Umall.
• 835 -All the country of Connaught was likewise desolated by them.
• 837 - A battle was gained by the Gentiles over the Connaughtmen, wherein was slain Maelduin, son of Muirgius mac Tommaltaig, with numbers of others along with him.
• 843 - An expedition by Turgesius, lord of the foreigners, upon Loch Ribh (Lough Ree, so that they plundered Connaught and Meath, and burned Cluain Mic Nois (Clonmacnoise, with its oratories, Cluain Fearta Brenainn, (Clonfert), Tir Da Ghlas (Terryglass), Lothra (Lorrha), and many others in like manner.
• 844 - A battle was gained over the Connaughtmen by the foreigners, in which Riagan, son of Fearghus; Mughron, son of Diarmaid; and Aedh, son of Catharnach, with many others, were slain.
• 847 - A fleet of seven score ships of the people of the king of the foreigners came to contend with the foreigners that were in Ireland before them, so that they disturbed Ireland between them.

During one such episode in 848, Maelan was slain by the foreigners. He is anachronistically referred to as lord of Ui Briuin of South Connaught.
