Help! Military records for Harry Elmer Smith WW1

[auntie bertie]

Trying to research a mystery man called Harry Elmer Smith - unfortunately there seem to be several men with that exact name!
Canada- Officers and Men in the First Canadian Contingent, 1914 - a Harry Elmer Smith joined CANADIAN 15TH BATTALION, 3RD INFANTRY BRIGADE #27540

In 1918 this same man married Marina Krijger in the Netherlands.
What I am trying to find are DoB records and Place of birth for this Harry so I can rule him in (or out ) as being 'my' Harry!

1. Harry Elmer Smith Birth   Sep 1885 Kerney, Nebraska, USA

2. Harry Elmer Smith Birth   Sep 1885  unknown but possibly Portsmouth UK-son of Harry Palmer Smith

3. Harry Elmer Smith Birth 1870 unknown but he married in 1896 in London UK, son of Jacob Smith

Thanks

Brilliant! Thanks so much.  So 'my' Harry didn't marry Marina - one question solved and the mystery of my Harry remains.

Unfortunately this has introduced a 4th Harry Elmer Smith born in Boulder City, Kansas who married Marina!
