The Senchus fer n-Alban (The History of the men of Scotland) is an Old Irish medieval text believed to have been compiled in the 10th century.
The Senchus exists in a number of manuscripts, of which the most important belonged to Dubhaltach Mac Fhirbhisigh and then to Edward Lhuyd.
Most versions of the Senchus follow the late myth of the Dál Riata origins by beginning with Eochaid Muinremar and the sons of Erc, Fergus Mór among them.
[4] The Genelaig Albanensium, and the similar genealogies in the Rawlinson B 502 manuscript, make Cairpre Riata an ancestor in the tenth or fifteenth generation of Fergus Mór mac Eirc.
[10] The Senchus lists no kindreds or military obligations for the Irish lands, if any, which may have formed part of Dál Riata.
