Thank you for that. You are correct - my mistakes -
re 1881 death of Eleanor also William died in 1891 at the home of his son Joseph. I have details re the Aust. born children, also Rebecca, but want to trace the 2 London born sons and their cousin, Jane Murray, born 1839 Dublin. The Melb.Cem. grave has a (moveable)plaque possibly placed there after WW1 (the cem. has no record of this). It states-
"Also our dear son and brother JIM Killed In Action 26 Sept.
1917". I have searched NAA/Honour Roll for the 57 men named Jim or James KIA that day and haven't been able to connect to the Murrays. There is a James Murray KIA near that date but after getting his Birth. Cert he is not the one. I have also trawled "Trove".By my reckoning "Jim" may be the son of a daughter of John or Henry with an unknown surname. So it is a mystery and the plaque may even be on the wrong grave. I found the possible marraige of Henry you mention and couldn't connect to "Jim" but I will endeavour to get the Death Cert of the John Murray 1919 and hope it has details so the mystery can be solved.
Thanks again, Irene.
