In Bretha Nemed Toísech(First Judgment of Privileged Ones) some of its composition is attributed to the accounts of three kinsmen, Fornannán(a Bishop), Máel Tuili (a poet), Báethgalach hua Búirecháin (a judge), who flourished during the reign of Cathal mac Finguine. This manscript mostly tackles legal matters concerning the early church and the importance of the role of ecclesiastical scholars, which is reflected also in the Uraicecht Becc and Collectio canonum Hibernensis both are connected with the Nemed school of law. The Collectio canonum Hibernensis was in created in both Iona Abbey and also at Dairinis near Waterford. A translated Old Irish copy was found among the Bretha Nemed Déidenach law manuscripts.
