Hi Raylen!
Your query was ten years ago but I believe the man you are looking for may be my grandfather. I have been doing a deep dive into tracking down his family history and if I'm correct, he indeed went by many aliases, I am now discovering! I'd really love to find out what you can tell me about his double/triple/quadruple lives, as my mother had no idea and only knew him by one name.
If your mysterious John Beckman is my grandfather, he died in 1964 in Ballarat, Victoria Australia. He had many siblings, most of them half-siblings, and I believe one full sibling. I believe I have found records for at least four children including my mother, and am scouring to find perhaps more.
If your grandmother was Maria 'Gertrude' Reidy, whom John was married to from 1914-1922, then I have found a John Murray Beckman b1914, Albert Petersen Murray Beckman b.1917, and David Murray Beckman, aka 'Beckman', b.1922.
If your grandmother was another of Beckman's marriages I would love to hear from you, hopefully together we can piece together some mysteries?
Hopefully you are still active here and we can connect.
Em
