William de Douglas, Lord of Douglas was born circa 1220 to Archibald Douglas (bef1198-c1238) and Margaret Crawford (-c1238) and died circa 1274 of unspecified causes. He married Constance Battail (-c1274) .
William, Lord of Douglas (c. 1220 – c. 1274), known as 'Longleg', was a Scoto-Norman nobleman.He was the son of Archibald I, Lord of Douglas
The years of the minority of King Alexander III (1249–1262) featured an embittered struggle for the control of affairs between two rival parties, the one led by the nationalistic Walter Comyn, Earl of Menteith, the other by pro-English Alan Durward, Justiciar of Scotia. The former dominated the early years of Alexander's reign. In 1255 an interview between the English and Scottish kings at Kelso led to Menteith and his party losing to Durward's party. Later both parties called a Meeting of the great Magnates of the Realm to establish a regency until Alexander came of age. William Lord of Douglas was one of the magnates called to witness. Douglas was a partisan of Durward's party. This can be explained by the fact that although most of his territories lay in Douglasdale, through his wife, Constance, he had obtained the rich Manor of Fawdon in Northumberland and it would do well to keep English Royal favour.
David Hume of Godscroft, the arch-panegyricist of the House of Douglas, states that Longleg married Marjorie, Countess of Carrick and had by her two sons and a daughter, the daughter inheriting the Earldom of Carrick. Marjorie went on to marry Robert the Bruce, father to King Robert I of Scotland; this, however, does not make any sense historically.
