I personally believe that the Lord Vessel was destroyed, judging by the shattered object in the mansion basement, and because of that, the souls offered to it (Four Kings/Gwyn, Seath, Bed of Chaos, Nito) escaped or have been removed. This could have caused the souls to find new hosts perhaps, or the new hosts found them, these souls could potentially have some recollection of their past experiences/memories causing the new hosts to repeat the same events and mistakes.

I also believe this has happened more than once since Vendrick supposedly "vanquished the four Great Ones, and built the kingdom upon their souls" implying that Vendrick has done the same as you.
