Thank you Cando, KGarrad and Sparrett.
Your posting summarises pretty well all I know. Much of my knowledge is third hand , oral history in the family. We all know how that can be misdirecting, even second hand!
I do not know whether James (Jimmy) and Elsie left England to live in Australia.
I think it was James and Muriel who emigrated to Australia, and were visited in the Melbourne area by another relative - distant to me - probably in the 60's. At this stage I am not sure if Jimmy and Elsie had 3 children; James (b. 1914), Margaret (b. 1922) and Donald (b. 1928).
To tell completely all I know, in the very back of my memory is a tale that Jimmy was found dead , collapsed behind a door, and Elsie died a year later. That fits with the record that a James Weir died at Cleveland in 1959 and an Elsie Weir at Cleveland in 1960. Search of the local papers has not yielded any information, as yet.
