I had taken it to indicate that the male forebear, John Mawby, had been the 18-year-old convict who had arrived in the penal colony in 1842.
But now I'm wondering if he was in fact the John (Joseph) Mawbey who was the 10-year-old convict before Hobart Quarter Sessions in January 1835.
Judging by their ages, the former was born c.1824 and the latter c.1825.
The Tasmanian Mawbey family historian said that John (Joseph?) Mowby was born in 1821.
He entered into a permanent relationship with Maria Inglis, b. 1836, and they produced at least one child, a son Nathan Mowby, b. 14.12.1874.
So John Mowby was 15 years older than his partner.
There is no marriage record, but Maria died named 'Mawbey'.
If they paired up when she was 20, and he was 35, this would have been in 1856.
But their son Nathan not born until 18 years later, when she would have been 38 and he 53.
There could have been another generation in between.
I will have to check this.
The Tasmanian Mawbey family historian appears to think her forebear was the John Mawby who arrived in 1842.
The convict boy, John Mawbey, was sentenced to 7 years transportation in 1835.
If he was sent back to England, he may have been the same one who arrived back in Tasmania in 1842.
Both of them were convicted of stealing, and coincidentally, both had stolen shoes.
I have not been able to find any records on any convict registers of the convict boy who was in Hobart in January 1835.
