But English titles are one thing, and French another, so below are the titles that my current WIP-- historical fantasy set in 13th century France--needed (courtesy of that fascinating melting pot of sources, quora.
The title of a knight is Chevalier. A lesser Knight, ( eg son of a knight) is an Écuyer .
The title comes after the name when y whole name.
Eg “Richard de Longeville, Chevalier”
Or “Jean de Longeville, Écuyer”
To be a Chevalier, you had to be a member of an “Order of Knights”
When speaking to a Knight, he would be addressed as “Mon Seigneur” (My Lord)
From which derives the modern day word Monsieur.
There were other titles for Knights who had land posessions;
Duc, Prince, Baron, Marquis. Compte. Viscompte
In English , Seigneur became anglicised into “Sir”
