Hi Crisane
Yes I think it is Arthur death
I found that to and was also looking at the voters list for both Louisa and Arthur
I found Louisa on her own on voters list,
1914, Yarra, Collingwood so went and had a look for Arthur on voters list and a possible death
found who I thought might be Arthur living in Geelong with a Anne on the 1914, Corio, Barwon voters list
did a bit more snooping and found they had a few other children
still unsure if I was on the right track found a couple of trees
and looks like it is correct
Arthur has left Louise and had been living with a Anne Ault
he has married her 9th July 1923
