When Mary was pregnant in Edinburgh Castle with her son James, Margaret helped draw up her will with a list of bequests of personal jewellery from her cabinet.
On 5 October 1565 the queen gave her a coffer and a length of taffeta, and in November and June 1566 material for black velvet gowns.
Buchanan's story, published to incriminate the queen, was that Mary lodged in the Exchequer House in Edinburgh rather than her Palace in September 1566.
One of the Casket Letters, which were thought to incriminate the Queen in the murder of Darnley, mentions Margaret Carwood and her previous departure from court.
[13] Hay's articles allege that there was no show of mourning clothes, and more enquiry made after money stolen from Margaret Carwood than for Darnley's murder, and the King was buried at night without ceremony.
[14] In March 1584 John Stewart and Margaret Carwood complained to the Privy Council about their land near Dunkeld, held from the estate of Dunfermline Abbey.
