| He appears as a witness to a charter by Adam, called Carpenter, granting Ingleston to the Abbey of Paisley, dated about 1260, and also to two writs by Walter Stewart, Earl of Menteith, dated respectively 19 January 1262-63 and 14 May 1271. Mr. George Erskine, Baron Bailie of Alloa, who, in 1709, wrote a short account of the family, refers to a charter which he believed to exist, but which he had not seen, granted to Sir John for services at the battle of Largs. Some time between 1300 and 1309, James, the High Steward, granted to John Yrskyn, son of John, son and heir of Sir John, certain lands in the holding of Largs, which shows that Sir John was then alive. He is therefore probably the Johan de Irskyn who appears among other landowners of Renfrewshire in the Homage Roll of 1296. A seal believed to be his is still attached, and is thus described: A stag's head cabossed ; between the antlers a small four-footed animal passant to sinister. Legend, 'S. Johannis de Erkyrn' (?).3 |
