I included Legolas as it too would still fall under the "disrupt the game" clause.
Two players both having male elves, and one picks Lagolas and the other complains because they want the name but didn't think it would be allowed...I have sen it happen. So best to leave well known names as off-limits for DM and PCs.
Names that are clearly from well known properties like Legolas, or that don't fit the setting, or are just plain silly are disallowed in my game.
a joke name makes for a joke character.
So to the OP's original point, if my world doesn't have PCs with "English" names, then the example names wouldn't fit and thus be disallowed.
