| He is designed Lord of that Ilk and of Tranent in a charter whereby he granted the lands of Wester Fausyde to John de Fausyde, his esquire. He seems to have granted certain lands in Longniddrie to John Maitland and John de Paynston by charter confirmed by King Robert II 18 January 1380-81. He was a distinguished soldier, and like his father he took part in the holy war, it is said before 1383; he seems to have served with the Scottish force which raided the north of England in that year. He styled himself 'Baron, lord of Seton' in a petition to the Pope which was granted 27 October 1394, but is designed Knight in a charter of the lands of Borde granted by him in favour of Patrick Fleming, dated 14 May 1402. It would seem that he was taken prisoner by the English at the battle of Homildon Hill 14 September 1402, and he may perhaps have remained unransomed for some years, as one William Seton was in captivity in the Tower along with the King of Scotland's son in 1406. A charter of confirmation was granted at Perth, 27 March 1408, by Robert, Duke of Albany, Governor ol the Kingdom, ratifying the grant of an annualrent made by William de Seton, Knight, with consent of the Duke's beloved cousin, John de Seton, Knight, his son and heir, to Walter de Haliburton of Dirleton, in consideration of the transfer to the said William of the gift of the ward and marriage of Elizabeth de Gordon, daughter and heir of the deceased Adam Gordon, Knight. Sir William died before March 1409-10, and was buried in the Cordelere (Franciscan) freiris at Haddington, to which community he had made certain benefactions.9 |
