Hi, I have a mystery which if possible I would like to solve. While searching my husbands FT I came across a John McCann born 23 Feb 1894, Londonderry to James and Mary McCann (nee Meehan).
John is still with the family in 1901 and 1911 census. The family appear to move to Greenock, Scotland between 1911 and 1915, Mary death records show this.
John appears to disappear. Quite by chance I come across a war memorial death record for a John Gallagher, who was killed 7 Jan 1919 in a mine explosion in the Thames Estuary. The memorial states that he was actually called McCann.
When I checked his service records on National Archives his next of kin was James McCann and the address matches that on Mary's death record. A note is on the record stating that James McCann had given proof to show that John Gallagher was actually John McCann. He had also changed his birth to 14 Aug 1896 and place of birth to Co Claire.
Who was he hiding from and why?



? How will I find out? Isn't family history exciting!!!!
