[1] Egidia was the daughter of King Robert II of Scotland by his second wife Euphemia de Ross.
[2] King Charles VI of France had "sent a certain most subtle painter to do her portrait and portray her charms, intending to take her to wife.
"[3] But the King of France and all other of Egidia's admirers lost out to the chivalric charms of William Douglas of Nithsdale (c. 1360–1391).
William was an illegitimate son of Archibald the Grim, 3rd Earl of Douglas and an unknown mother,[4] and was reportedly dashing with a statuesque physical appearance.
[4] Part of Egidia's marriage portion were the lands of Nithsdale in south-western Scotland, Herbertshire in the county of Stirling and an annuity of £300.
