Seeking old soldier - J Callahan (Callaghan?), 3rd Canadian Military Police in 1946

[Tony Ward]

I dearly wish to contact J. Calla(g)han an ex-serviceman of 3rd Canadian Military Police, who was stationed in Alton/Odiham area of Hampshire, England in early 1946. He would now be in his mid-seventies or older if still alive. I have important information that will be of great interest to him or his surviving relatives.

Can anyone help, please?
