Before the Black Douglases: King Dubh and the Gaelic Memory of Lineage (c. 900 – 1174)

This paper examines the pre-feudal origins of the Douglas identity by tracing its linguistic, dynastic, and symbolic roots to the Gaelic monarchy of Alba. Centred on King Dubh mac Maíl Coluim (r. 962–967), it argues that the later Douglas name (Dubh-glas, “dark stream”) emerged from a native tradition linking royal epithet and landscape toponym. Drawing on Gaelic annals, place-name strata, and early diocesan records, the study situates the Douglas prototype within a continuum of native legitimacy and dark-water symbolism connecting the Dubh kingship of Alba to the Dubglas charters of the Clyde. It also outlines a multi-disciplinary verification framework integrating documentary, archaeological, genetic, linguistic, and liturgical evidence.
