She was the daughter of John Campbell, of Mamore, and the sister of John Duke of Argyle, the friend and patron of Duncan Forbes; and she had been, by Lovat's introduction, for some time a companion of his first wife.[215] Lord Lovat, about the year 1732, became a widower. He then cast his eyes upon the ill-fated Miss Campbell, and sought her in marriage. The match was of great importance to him, on account of the family connection; and Lord Lovat had reason to believe, that whatever the young lady might think of it, her friends were not opposed to the union. She was staying with her sister, Lady Roseberry, when Lovat proffered his odious addresses. She to whom they were addressed, knew him well: for she entertained the utmost abhorrence of her suitor, and repeatedly rejected his proposals. At last, he gained her consent to the union which he sought, by the following stratagem. Miss Campbell, while residing still with her sister in the country, received a letter, written apparently by her mother, and, beseeching her immediate attendance at a particular house in Edinburgh, in which she lay at the point of death. The young lady instantly set out, and reached the appointed place: here, instead of beholding her mother, she was received by the hated and dreaded Lovat.[216] She was constrained to listen to his proffers of marriage; but she still firmly refused her assent. Upon this, Lord Lovat told the unhappy creature that the house to which she had been brought was one in which no respectable woman ought ever to enter;--and he threatened to blast her character upon her continued refusal to become his wife. Distracted, intimidated by a confinement of several days, the young lady finally consented. She was married to the tyrant, who conveyed her to one of his castles in the North, probably to Downie, the scene of his previous crimes. Here she was secluded in a lonely tower, and treated with the utmost barbarity, probably because she could neither conceal nor conquer her disgust to the husband of her forced acceptance. Yet outward appearances were preserved: a lady, the intimate friend of her youth, was advised to visit, as if by accident, the unhappy Lady Lovat, in order to ascertain the truth of the reports which prevailed of Lord Lovat's cruelty. The visitor was received by Lovat with extravagant expressions of welcome, and many assurances of the pleasure which it would afford Lady Lovat to see her. His Lordship then retired, and hastening to his wife, who was secluded without even tolerable clothes, and almost in a state of starvation, placed a costly dress before her, and desired her to attire herself, and to appear before her friend. His commands were obeyed; he watched his prisoner and her visitor so closely, that no information could be conveyed of the unhappiness of the one, or of the intentions of the other.[217] This outrageous treatment, which Lord Lovat is reported, also, to have exercised over his first wife, went on for some time.
