I just got word that a cousin has a copy of Albert "Allie" Murray's marriage certificate to Agnes Dalton! I hope it will help me further with my efforts to uncover more about Allie (or Alley). I wrote about my initial research here:
Albert Murray, aka Edward Mallory. At the time I wrote that post, it seemed the Dalton Gang connection was unlikely, despite family stories. But maybe the marriage certificate will yield some clues. Stay tuned!
