He was related to the ancient and honourable family of the Oswalds of Sheildhall, and received that excellent educational and religious training which is given to the children of the middle and higher classes in Scotland. At the age of twenty-two or three, in consequence of an attack of pulmonary hemorrhage, he sailed for the West Indies and found employment at his trade, house-building, in St. Kitts. Very soon, however, he found other matters to engage, and almost engross his attention and labours; in conjunction with an uncle of George Stephen of London, and a Dr. Hamilton, resident in St. Kitts, he did manly and successful fight in behalf of the wronged and bleeding slave. After a residence in that island of some years, during which he obtained a thorough knowledge of the workings of slavery, he returned to Glasgow, poor in pocket, but rich in abolitionism. Soon after his return, he was united in marriage to Miss Anna ——, a lady whose perfect harmony in sentiment, softened by feminine delicacy, made a happy anti-slavery home for the zealous and ardent abolitionism of John Murray. It was a union of hearts attached in early youth, and which had remained “leal” during a long separation. Shortly after marriage, he commenced business as a _spirit-dealer_, then and now a most reputable calling in the opinion of the good citizens of Glasgow. Temperate himself, his calling gradually became unpleasant to him. At first he refused to sell spirits to any person partly inebriated; then he reasoned himself into a total abandonment of the death-dealing traffic. With no other business prospect before him, prevented by his long difficulty from working at his trade, with a young wife and child dependent on him, he suddenly locked up his spirit-cellar and never more sold rum! In 1828 or 1829, through the influence of his kinsman, James Oswald, Esq., of Sheildhall, Mr. Murray was appointed surveyor on a part of the Forth and Clyde canal, an office requiring much labour for little pay. His prospects of promotion depended on Mr. Oswald and other members of the Kirk of Scotland. Mr. Murray was a full member of the Tron Church, Glasgow, when, according to law, a minister was appointed there regardless of the choice, and contrary to the wishes of the great majority of its members. In consequence of this appointment, and again unmindful of personal advancement, John Murray shook the dust from his sandals and quit at once and for ever the Tron Church and the Kirk of Scotland.
