Hi,
Maude is listed at Hamilton Creek Road in 1913 and in 1922 so it was obviously her main address..
That doesn't mean she was actually living at that address in 1921,,,would mean if she moved she didn't bother changing her contact details with the Electoral office.
Is this her marriage(s)
1907/C2412 Sayers Maud Constance Jackson James
1928/B3010 McDonald William Glasford Jackson Maud Constance
