LYLE, Lord Lyle.
SOme who have enquired into the Antiquity of Sirnames with much Curiosity, think that the first Ancestor of this Family was one of those Scots|men who fled from the Usurpation of Mackbeath into England, and returned with Edgar Atheling and his Sister the Princess Margaret, afterward Wife to King Malcolm Canmore, upon the Inva|sion by William the Conqueror, and got Possessions in the Isle of Bute, in the Western Parts of this Realm, from whence they took the Demonation of Le Isle, which they kept after they came to be settled upon the Continent at Duchal-Castle in Renfrew-shire. Tho I have not seen directly any Mention of them till King William's Time, that William de Isle is one of the Witnesses to that Deed, which Walterus Dapifer Regis made to the Monks of Paisley, when he founded that Convent of the Lands of Espindera 1.1. He is the same Person, as I take it, who is one of the Barons taken Prisoner with King William at the Battle of Alnwickb 1.2 on the 13th July 1174.
The next in order of Succession, if not his Son, to be taken notice of is Radulphus de Isle, who is a Witness to the Donation, which Baldwin de Bigris, Sheriff of Lanerk made to the Abbot and Convent of Paisley, and to the Monks serving GOD there, as the Gift bears, in pure Alms, Ecclesiam de Innerkip cum tota illa terra inter tumulos ubi Ecclesia est fundata, ita libere sicut di|cti Monachi possident reliquas Ecclesias de Strath-Grief, ex dono Walteri filii A|lani-Dapiferi Regis Scotiae.
The next of this Lineage is Alanus de Isle, who is a Witness to that Ex|cambion which Walter High Steward of Scotland made of the Lands of Ky|lingtoun for the Lands of Innerweek, the Tithes of which he made over to the Abbot of Paisley, for the Welfare of him|self and his Successors, both here and hereafterc 1.3. He is also to be found in the Confirmation which Alexander High Steward of Scotland made to the Monks of Paisley, of all the Donati|ons made by himself or his Ancestors down to that Period of Time, in the Year of our Lord 1151.
Radulphus de Isle, Insula, dominus de Duchal, probably the Son of the for|mer, is Witness to the Vendition of the Lands of Aldingstoun to the Abbot of Paisley, and his Title being added to the Sirname, is an undoubted Evidence that he was then a very remarkable Person; for I cannot but observe, that this is the very first time I have found any in the Western Parts adding a lo|cal Title to the Sirname.
