There seems to be a link between the name of Ricardi Edzear and the King of Scotland and his relations having land etc. in Mortoun, Nithdale.i.e. Reg. of the Great Seal of Scotland AD1306-1424, page 547. (my rough translation): #565.Charter to Christine de Cairnis the land of Mourtoun (confirmation Cristine Flemyng). # (3) Charter to Christian Bruce the kings daughter.
# (2) Charter to Thomas Ranulph of the barony of Mortoun, in valley de Nithdale, Dumfreis.(bro. of the King of Scot.?).
page 611, # (43) To George Dunbar, of the half of the barony of Tibris and Mortoun, in vicecomitatu of Dumphreis. Dunbar was a cousin to the earlier King of Scotland through Gospatric Edgar, cousin of King Malcolm. Perhaps may be further reference under the History of Dumphries, and the lineage of the Monarchs of Scotland.
