- Nomenclatorial Remarks
- <p>From the Old Welsh combrog = compatriot.</p> <p>According to Geoffrey of Monmouth in the first part of his pseudohistory Historia Regum Britanniae, the Trojan Brutus had three sons among whom (having subdued Gogmagog) he divided his lands after landing in Britain. His elder son, Locrinus, received the land between the rivers Humber and Severn, which he called Loegria (a Latinization of the Welsh name Lloegr, "England"). His second son, Albanactus, got the lands beyond the Humber, which took from him the name of Albany (Yr Alban in Welsh: Scotland). The younger son, Camber, was bequeathed everything beyond the Severn, which was called after him "Cambria".</p>
