mfw when i don't have any names. anyway i'll talk about the surname "Lorca" then... It doesn't have any specific meaning, but it comes from a little town in Murcia, Spain that's named "Lorca". A knight named Pero Fernández was sent over to Lorca for guarding purposes, and they called him Pero Fernández de Lorca ever since. So it just kept multiplying with his legacy, I suppose. Any knight that was sent over to Lorca for a permanent or semi-permanent amount of time also got assigned the "de Lorca" denotation, so it spread. :)
