By birth Jeanne was connected to Clan Forbes. The marriage seems to have taken place a few years before Clan Leslie joined with Clan Gordon in their feud against Clan Forbes. The Leslie's were supporters of Mary, Queen of Scots, Catholic pretender to the throne of England, who was imprisoned (and eventually executed) by Queen Elizabeth I and her son, the future James I of England, taken away to be raised protestant. These events may or may not have something to do with the later accusations that Thomas was an intelligencer for James I.
