After her marriage "Madamoiselle de Semple" was appointed lady of the bedchamber, an office for which she received £200 a year. Her husband also seems to have retained some office which required his personal attendance on the Queen, for we know that both husband and wife were in waiting at Holyrood on the memorable evening of David Rizzio's murder. The shock which this tragic event produced on Mary was very great, and filled her with the darkest forebodings. She more than once expressed her fear that she would not survive her approaching confinement. About the end of May or the beginning of June, shortly before the solemn ceremony of "taking her chamber", she caused an inventory of her personal effects to be drawn up by Mary Livingston and Margaret Carwod, the bedchamber woman in charge of her cabinet, and with her own hand wrote, on the margin opposite to each of the several articles, the name of the person for whom it was intended, in the event of her death and of that of her infant. Mary Livingston's name appears by the side of the following objects in the original document, which was discovered among some unassorted law papers in the Register House, in August, 1854:-- Quatre vingtz deux esguillettes xliiij petittes de mesme facon esmaillez de blancq.
