Thanks Carl
Here are the two nobles i'm struggling with, I know they were assigned to defend Therouanne but other than their company sizes that's it;
Compagnie du seigneur de Sercu : 500 hommes de pieds
Compagnie du seigneur de Hely : 500 hommes de pieds
I don't know their names or heraldry.
Also, am i right in guessing that 'hommes de pieds' is infantry?
