Sir Alexander Stewart, Earl of Menteith - Wife identified

Previously, the wife of Alexander, Earl of Menteith (son of Walter) was shown in Geni as Matilda de Arnot, who was thought to have married Sir Simon de Haldane second.

But there’s been a significant article from John P. Ravilious, placing her a Matilda, sister of Malise, Earl of Strathhearn.
