I am hoping to find out what happened to my great grandfather, Nicholas Johns Trevena b. 1884 at Canterbury NSW Australia (BDM 5781/1884), he married Estelle May Curr at Burwood NSW Australia 19th March 1903, they divorced around 1916. The last record I can find of him is the decree nisi in 1921, after that he was never seen or heard of, can anyone give me any information or steer me in the right direction to find out what happened to him? I have been to the local genealogy society but to no avail. Thanks in advance.
