Thank you to everyone for all the work you're all putting into this mystery.
There are 4 cousins currently trying to understand the relevance of what you've all put forward.
2 of those are granddaughters of Walter Clem and Violet, children of James Ralph Matthews and Lillian Tiffen and the other 2 are granddaughters of Amy Ellen Rose Gleed.
Can you account for all the males and females of child bearing age who are named on the dc for James who died Ascot Vale on 23 May 1922 .... see reply #87 on other thread
... so wondering if a daughter or daughter in law may have been Amy's mum, but was known informally as Alma ...
1922 Olive was 16 ... she was 11 going on 12 in Jan 1918 .... so start with Violet, then Nora Ellen, Ivy Lily, and then Natalie May ... then look for possible VIc based partners for Walter Clem in 1916-17 and Herbert William in 1916-17..., born Jan 1918, so basically you are wanting answer to where was Alma over Easter 1917...

JM with reference to your comment;
In 1916/1917 the Matthews family were still living in Ridgley,Tasmania.
They moved to Ascot Vale,Vic in 1918.
My Grandfather Walter Clem Matthews was born 9 Jan 1902 TAS BDM Reg No.44026/1902
In 1917 he would only have been 15.
