Hello guys, for my timeline, the Reign of King John of France, I intend to have Enguerrand de Coucy meet Princess Margaret of Scotland (b.unknown - 1346/1347) , a daughter of Robert I of Scotland. I search over Wikipedia and the net and only found that she died around 1346/1347. Most of information was about her sister Marjory of Scotland. Is it to me to invent a birth date for my story or do something else ?
Any help will be much appreciated !!
