Suibhne mac Duinnshléibhe

Suibhne mac Duinnshléibhe was a late 12th-century, and early 13th-century, lord in Argyll. He does not appear in contemporary records, although his name appears in the patronymic names of two of his sons. Suibhne appears in the 16th century Leabhar Chlainne Suibhne, which documents the early history of Clann Suibhne. This account claims that he is the ancestor of Irish clan Mac Sweeney (Suibhne), and that he was the builder of Castle Sween in Knapdale, Argyll.
