Love a lot of these names! Surprised Arthur isn't on the list :O. I love Paladin--I'm going to have to add that to my list!! I didn't think it was a name, but it's so cool because of the class from MapleStory is B.A ;).
Thinking of LoTR meets Narnia:
The rics: Leofric, Emmerich, Elric, Aldric, Audric
The Fins: Finn, Flynn, Griffin, Finnegan
The Cas: Cassius, Caspar, Caspian
The Flower Boys: Florin, Florian, Fiorello
Zeref (I don't think it's a real name--it's from FT, but I think it works)
Drago/Draco - Personal GP
Names from my own list that might fit the bill:
Amias, Archer, Arthur
Casimir, Caspian, Cedric
Edmond, Edric, Edwin, Elias, Emmerich, Evander, Everard
Lancelot, Leander, Leonardo, Leopold, Loxley
Marius, Matthias, Merrick, Mirek, Milos
Rhys, Robin, Roman, Rupert
Thaddeus, Theseus, Tristan
Viktor, Viggo, Vladimir
Adding a few I forgot:
Larkin, Liev, Lorencio
Sorry for any repeats!
Awesome list once again! Emrys is of course my favorite :)
What do you know about the name Calidore? I know it has some literary uses, but do you know if there is actually any history of it as an actual real world name at some point? And do you know what it means? I'm curious, I really like the sound of it a lot a lot, but I can't find much information about it online (aside from it's use in The Faerie Queene).
Here are some others that maybe aren't specifically 'medieval/knightly' (I don't know), but give me that general impression (sorry for any repeats).
Nothing to add (sorry, don't know many unusual names compared to most Berries!) but wanted to say how much I'm loving this thread! So many names I haven't heard of before. I particularly like Calidore, Roscelin and Fiorello. Thanks everyone and especially Ottilie for starting it!
Most the names I wanted to add have already been suggested so my list is quite short.
Hugh, Giffard, Esdras, Douglas, Jac and Conrad all have this feel to me.
