Here's a tidbit I heard from my dad, who is a math professer.  The Borromean Rings are a mathematical concept that involves three rings, interconnected so that if one is taken away, the other two become unconnected.  Though the spelling is different, Tolkien may have had this theory in mind when he created the characted Boromier.  Consider that when Boromier died, the Fellowship was broken.  I'd love to hear your thoughts on this.
