In a previous post on my great-grandfather, the New York City Municipal Policeman I included a photo comparison of an image from our family album and one from a page of the book “The New York Irish” that I believe to be him.
Now, unprecedented in Tierney family research, I have updated that comparison with new and intriguing evidence. I leave you, dear reader, to form your own opinion of the great importance of this finding. Thank you and good night.
