Sir John Stewart, 1st Seigneur d'Aubigny - Battle of the Herrings AKA the Battle of Rouvray, per Wikipedia

"The Battle of the Herrings, also called the Battle of Rouvray, was a military action near the town of Rouvray in France, just north of Orléans, which took place on 12 February 1429, during the siege of Orléans in the Hundred Years' War.

"(Killled in the Battle of the Herrings OR Battle of Rouvray.)" for me, the "or" implies he died at one of two battles, and that the history is unclear on that point. I had to consult Wiki to settle the issue. FYI
