Thank you all for your help, the War Record that I found was a brief report of ill health after the war, there may be more there somewhere to find at another time.
Thought maybe Joseph died and Ellen remarried, but have found no records to support that theory, a Robert Martin married an Ellen, 1887 I think it was, but wrong surname for bride. On the 1911 census a Martin family father Robert wife Ellen married 24 years with son Edward age 25 and 3 daughters Edith 21, Lilly 19, and Grace 14 (on 1901 census Lilly is Elizabeth, Ellen's mother's name) and Grace is used as name for daughter born Sept 1919 to Edward Naphtali/Martin and Lillian. Which is probably all just a coincidence and not the family I am looking for at all, but the search has been enjoyable.
So will order the marriage certificate of Edward Naphtali/Martin and Lillian M Briers and see if there is any clue hidden away there.
Justin, Thanks for the family of Joseph, the switching of first to second names and vice versa is very confusing, don't suppose there would be any records of a Rebecca Hyman c1814 with a father Mordecai/Marcus in there somewhere? Need all the help I can get with that family.
Have been sent details of an "Ask a Librarian" service in WA so will sort out some questions for them to fill in some gaps.
Cheers
