premise: Jean le Fèvre de Saint-Remy or Jean Lefebvre de Saint-Remy (c. 1394 – June 16, 1468) born in Abbeville, was a Burgundian chronicler during the Hundred Years' War and lord ("seigneur") of Saint Remy, la Vacquerie, Avesnes and Morienne. He is also known by the formal title of authority "Toison d'or" (Golden Fleece) because he served as the King of Arms to the Order of the Golden Fleece.
hypothesis: He was born in 1300 + 52
reason: 1300 + 52 = 1352, he was born in 1394 not 1352. I think the model gets confused by addition math.
