Here's a challenge in resolving conflicting evidence
A US census record taken on Friday 15 April 1910 showing a boy aged 10
A Canadian province civil registration certificate for a marriage on Thursday 1 June 1922 showing his age as 23
A Canadian military attestation paper showing him enlisting on Friday 12 May 1916 with age given as 18 years and birth-date Friday 31 December 1897. The minimum age for enlistment was 18.
A US state birth certificate showing Monday 2 January 1899 as his birth-date registered on the last day allowable before a penalty for late registration had to be paid.
