Hi Keith,
William Bliss is my 5th great grandfather. In chronological order, we have William>Joseph>Henry Alonzo>Earl J.> Robert Henry, my great grandfather. All are deceased. I believe that the Aaron Bliss volumes contain a snippet that my grandmother and great grandmother submitted on the family to help, although they do not appear to be related to the rest of the Bliss line, as you stated. Feel free to contact me, as the grandparents who submitted the information are deceased and I am the main person keeping up the info (as far as I know.)
Many thanks,
rubyscarab
