Alexander Montgomerie, 6th Earl of Eglinton

Alexander Montgomerie, 6th Earl of Eglinton (1588–1661), originally known as Sir Alexander Seton; succeeded his cousin Hugh, 5th Earl of Eglinton, who, having no issue, made a resignation and settlement of the earldom and entail on Seton provided Seton took the name and arms of Montgomerie, 1612 (confirmed by King James VI of Scotland in 1615). Montgomerie petitioned against the imposition of Common Prayer Book in Scotland and assisted in the preparations of the National Covenant. He was a Privy Councillor of Scotland, 1641; commanded a Scottish regiment of horse (cavalry) for the English Parliament and distinguished himself at the Battle of Marston Moor (1644). On the execution of Charles I in 1649 he supported the recall of Charles II and the policy of the Marquess of Argyll. In 1651 he was betrayed to Oliver Cromwell and detained in Edinburgh Castle, but afterwards allowed the liberty of Berwick. His estates sequestered for two years, and he was included in Cromwell's Act of Grace.^[1]
