I am looking for some sort of legal confirmation of the birth of my father, Reid Lamar Hudson, in Cardston, Alberta on December 30, 1927. The problem I am having is that he was named Claude Rawlins Hudson on his birth certificate (of which I have a copy) but he never used that name. His parents were Clara Rollins (shows "Rawlins" on my dad's BC) and LeRoy ("Roy") Hudson. I am trying to find legal confirmation that Claude Rawlins and Reid Lamar were one and the same. The hospital in which he was born no longer exists, I understand. Any help would be appreciated.
