Background His father, also Jérôme Groslot (1520–1572), was killed during the St. Bartholomew's Day massacre in Paris. Jérôme Groslot came to Scotland and was brought up for a time with the young James VI at Stirling Castle.Alexander Courtney, James VI, Britannic Prince: King of Scots and Elizabeth's Heir, 1566–1603 (Routledge, 2024), pp. 31, 105.Gareth Russell, Queen James: The Lives and Loves of Britain's First King (London: William Collins, 2025), p. 49. In Scotland, Jérôme Groslot was sometimes known as "the son of the Baillie of Orleans".David Agnew, Protestant Exiles from France: Refugees naturalized before 1681, vol. 1 (1886), p. 104. His sister Louise married Samuel Puchot de Bertreuille in 1601.

Diplomacy Groslot returned to France in 1581 and George Buchanan, his former tutor, wrote to Theodore Beza on his behalf. He visited Oxford and Cambridge universities with Paulus Melissus.David Agnew, Protestant Exiles from France: Refugees naturalized before 1681, vol. 1 (1886), p. 257.
