ShaunJ I can’t thank you enough for sharing all this information

The newspaper report is really concrete evidence of the demise of Charles Bureau, the date fits with the rest of the story & why he cannot be found in the following years. The report says the men were buried at sea the same day. I’m just wondering about the death certificate as I’ve not been able to find any record of one, would this be specially recorded by the RN & not by the usual method do you think?
Thanks amongd for your contribution although I tend to agree with ShaunJ that Quebec was a British colony at that time, so despite being born in Quebec Charles would still be considered British. Looking back through UK records to find any UK based parents of Charles, I’ve drawn a complete blank & as I mentioned at the beginning of this thread in the 1841 census I see several entries for Bureau, but the head of the household in Montague with no mention of a Charles or John.
ShaunJ I’ve previously seen the 1822 baptism entry & wondered if it’s relating to my ancestor or not, points for are the fathers name John & occupation which are the same as Charles’ wedding certificate although I’m imaging both were commonplace at the time?
Points against is Charles name is not the same as used in UK although this could be just a simpler form, just using the name Bureau alone often makes things complicated in UK! Also the date of birth is 1822, in the 1851 census Charles gives his birthdate as about 1823 & unfortunately in the wedding certificate it’s illegible, looks more like a word than a number, so my guess is it’s an abbrev for of age or something similar?
I contacted the Quebec Geneological Society a few months back & they said the surname Bureau is very common in Quebec & for the years 1669-1849 they have over 2000 entries, they said the baptism entry is the closest they have to the date 1823 for a Charles Bureau.
The only other way I can think of to confirm parents details would be if any of this information was documented when he joined the RN.
Many thanks once again!
