Easy mistake to make, there were so many similarities, Mark !

Mary Boyd b. Oct qtr 1882, bap 22/11/1882 St Anns Church, Newcastle upon Tyne.
Couldn't come up with anything at all for Mary apart from a couple of possibilities for marriages. Even then it was hard to tie in the information with the census.
But ... after all that I've found a tree on Ancestry.
Haven't a clue whether this is factual or not, but still might be worth your while to see it :
Marriage 1912
Mary Boyd, aged 30
Frank Richardson
Sydney, New South Wales, Australia
Death 20th April 1961
Mary Richardson, aged 78
Sydney, New South Wales, Australia
To be taken with a pinch of salt unless anyone can prove otherwise.
