In the month of May, 1566, Mary Beton married Alexander Ogilvie, of Boyne. But little is known of this marriage beyond the fact that the Queen named the day, and beyond such circumstances of a purely legal and technical nature as may be gathered from the marriage contract, which is still extant, and has been published in the Miscellany of the Maitland Club. It sets forth that the bride was to have a dowry from her father of 3000 merks, and a jointure from her husband of lands yielding 150 merks and 30 chalders of grain yearly. This legal document derives its chief interest from bringing together in a friendly transaction persons who played important and hostile parts in the most interesting period of Scottish history. It bears the signatures of the Queen and Henry Darnley, together with those of the Earls of Huntly, Argyll, Bothwell, Murray, and Atholl, as cautioners for the bridegroom, that of Alexander Ogilvie himself, who subscribes his territorial style of "Boyne" and that of "Marie Bethune". The signature of the bride's father, and that of Michael Balfour, of Burleigh, his cautioner for payment of his daughter's tocher, are wanting. It would appear that Mary Beton, or, as she was usually called after her marriage, "the Lady Boyn", or "Madame de Boyn", did not immediately retire from the Court. In what capacity, however, she kept up her connection with it, cannot be ascertained. All that we have been able to discover is that after her marriage she received several gifts of ornaments and robes from the Queen. Amongst the latter we notice a dress which was scarcely calculated to suit the fair beauty: "Une robbe de satin jeaulne dore toute goffree faicte a manches longues toute chamaree de bisette d'argent bordee dung passement geaulne goffre d'argent!"[96] Both Mary Beton and Alexander Ogilvie are said to have been living as late as 1606. All that is known as to the date of her death is that it occurred before that of her husband, who, in his old age, married the divorced wife of Bothwell, the Countess Dowager of Sutherland. It is interesting to note the contrast between the comparatively uneventful reality of Mary Beton's life and the romantic career assigned to her in one of the best-known works of fiction that introduces her in connection with her royal and ill-fated mistress. In Mr. Swinburne's _Mary Stuart_, the catastrophe is brought about by Mary Beton. For some score of years, from that day forth when she beheld the execution of him on whom she is supposed to have bestowed her unrequited love, of the chivalrous, impetuous Chastelard, when her eyes "beheld fall the most faithful head in all the world", Mary Beton, "dumb as death", has been waiting for the expiation, waiting Even with long suffering eagerness of heart And a most hungry patience.
