I believe that the Old Dragonslayer might in fact, be Ornstein. Gwynevere is an illusion in Anor Londo. It's quite possible that Ornstein and even Smough are Illusions too, despite the fact you can absorb their souls.

Also, Ornsteins armor and the old dragonslayer's are different colors. Ornstein's is Gold, while the Old Dragonslayer's is Silver. If you look at the other three Knights of Gwyn (Gough, Ciaran, and Artorias) all of them have Silver plated looking armor, except for maybe Gough.

Another thing to look at, is the age. By the Present time in Dark Souls 1, Ciaran and Gough are dead. But Ornstein is alive and well. but the Old Dragonslayer, is as the name says, very old. and he drop the old Leo Ring.

They both have the same armor, same title, and same ring. What are the odds? The only difference is the color.

Well this is my theory.
