From the time of the death of his grandfather, Hugh, in 1669 he was boarded with Matthew Fleming, the minister of Culross, Perthshire, who superintended his education at the school of Culross until 1673, when he was sent to the University of St. Andrews, where he remained till Lammas 1676. Montgomerie was a keen freemason.[1]
Career
After the revolution he was chosen a privy counsellor by King William, and also a lord commissioner of the treasury. In 1700, he obtained a letter from the king to sit and vote in the Scots parliament in place of the lord high treasurer.
He succeeded to the earldom on the death of his father in 1701.[2] On Queen Anne's accession in 1702, Eglinton was chosen a privy counsellor, and in 1711 he was named one of the commissioners of the chamberlain's court.[citation needed]
In 1710, and again in 1713, he was elected one of the Scottish representative peers. George Lockhart, who was his son-in-law, stated that when he himself proposed to bring in a bill for resuming the bishops' revenues in Scotland, and applying them to the episcopal clergy there, Eglinton gave his support to the measure, and assured Queen Anne that Presbyterians would not actively oppose it.[3]
This is corroborated by Wodrow, who asserts that Lockhart, either in the House of Peers or in the privy council, proposed 'that as we are one in civil we should be one in church matters'. Wodrow also states that his speech on patronage and toleration was 'so very good' that it was supposed 'it was done by somebody for him'.[4] In June 1712, he also proposed a bill for prolonging the time for taking the oath of abjuration till 1 November.[2]
In the early 18th century is town residence stood at the head of Old Stamp Office Close on the Royal Mile in Edinburgh.[5]
Lockhart affirms that Eglinton at last professed himself a Jacobite, and promised him three thousand guineas 'to help the Pretender in his restoration'. Wodrow also relates that shortly before the rebellion in 1715 Eglinton was at a meeting of the Jacobites where the rebellion, as to the manner of carrying out, was concerted, and heard all their proposals'. Nevertheless, during the crisis he raised and disciplined the Ayrshire fencibles, with which, on 22 August, he joined the Earls of Kilmarnock and Glasgow and Lord Semple at Irvine in support of the government.[6]
Personal life
Eglinton was married three times. A few months after leaving the university he married Lady Margaret Cochrane, eldest daughter of William Cochrane, Lord Cochrane, the son of the William Cochrane, 1st Earl of Dundonald, on which occasion his father made over to him the Eglinton estates.[1] By his first wife, he had three sons and six daughters, including:
Hugh Montgomerie, styled Lord Montgomerie, who died in 1696.
He died suddenly at Eglinton on 18 February 1729. Between nine hundred and a thousand beggars are stated to have attended his funeral, £50 being divided among them.[2] He was succeeded by his son, Alexander.
