I've had a small seed of doubt about the George we found, even when my distant cousin first told me about him, but he does add up. I understand what you're saying about him probably lying about his age on the marriage certificate - he probably had his reasons. It's just that I can't find any connection for him to the sea. The family believed he came from Devon to Australia, but I can't find any Devon connection to our George.
My cousin sent for his death certificate but she found out that the information on the certificate was given by a neighbour who said George was born in Derby. My cousin felt certain this was our George too.
I don't think there's a headstone, but I'm not sure. It's just that his grave didn't show up in the memorials search, only in the cemetery burials record my cousin found.
The only information on my grandfather's (Walter) birth certificate is George's and Ellen's names, profession of father, and residence of parents.
I haven't checked all the convicts records - it's going to take a lot of time. I'll finish the family tree and sign up with Ancestry.com for a month because I have a German great grandfather on my mum's side to chase up. I want to compile as much information as I can before I sign up so I can get as many details as possible in that time.
Thanks for keeping me on the straight and narrow. Happy supplies day tomorrow
