Jamjar, that is SO EXCITING!!!
John James' brother, William Henry Burt, had a daughter, Mary E BURT, born in 1872 in St Columb Minor, Cornwall. A great Aunt (also named Mary but known as May, interestingly) said that she had apparently died aged 17. But I had been unable to find a death that I could confirm was hers (and she wasn't on the 1891 census). So May could be Mary! I just need to find her coming to Aust. Her father died in 1880 you see, and the children were a bit spread out after that, so it is possible that she came to Aust for a new life.
I don't know where Mark is buried, but he died in Drummoyne.
I can't find any close relationship to a Thomas family, unless Ann Jane's mother Eliza was one, haven't looked into that bit yet. John James' bro William Henry, married Mary Williams (no relation to Ann Jane) whose mother was Mary Thomas. But that's a bit longwinded isn't it!!!!
Wow, I am so excited about this. Other than Mary Burt born in Cornwall there is nobody that I know of who fits that bill!
Thank you so much Jamjar!!!
