i am currently researching the Lazarus family from Llanbedrgoch, Anglesey. My main interest is Thomas John Lazarus b 1894, d 1943 in Canada. I know he was in the merchant navy and rumour has it that he drowned at sea?

? The last record that I Can find for him in the passenger crew list is from 1941, but don't know what happened to him after that.
I know which cemetery he is buried in Canada, but is to possible to order a copy of his death certificate.
I would be interested if anyone knows anything about this family, interesting stories etc.
Thank you in advance for your help.
