The British Army Service Record for Anthony Hamill shows his address as 15 Nelson Street Maryport, same as the last UK census. Marine Store Dealer. It also confirms that he was tattooed - anchor and star right arm - true love and dagger left arm. Regiment No 74777 - Royal Field Artillery.
Can't see any passenger list to Canada or the USA showing Anthony Hamill born 1897. Have tried variations of the Hamill/Hammill/Hamel/Hamel surname but so far nothing.
Unfortunately there are no Central registries/indexes in Canada for BMDs. Canada has very strict privacy laws and each province imposes its own even further. Additionally, some provinces are more research friendly than others so researching in Canada can be challenging. The latest available Canadian Census is 1921 As a guide BMD Records are only available for births more than a 100 years ago, marriages 85 years ago (up to about 1930 at present) and deaths 70 years ago. Sometimes by using newspaper announcements, cemetery records, obituaries, telephone directories we can manage to find information but you can see how difficult it can be.
