Mothe-Fénelon was involved the exchanges of gifts and portraits between the English and French court, including the work of the François Clouet and possibly Nicholas Hilliard.
[4] In 1574 Mary, Queen of Scots embroidered an incarnate satin skirt with silver thread using materials bought in London by Mothe-Fénelon.

[11] In September 1574, Fenelon received a letter from the former Regent Arran, now known as the Duke of Châtellerault, and a small portrait or miniature of James VI of Scotland, probably derived from a work of Arnold Bronckorst or an artist recorded as the "French painter".
[21] The English diplomat, Robert Bowes and William Davison, reported that Mothe-Fénelon and Maineville were trying to build a French faction in Scotland, help by the financial insecurity of the Ruthven Regime.
