I am not convinced that the chap on the Mangels into NSW in 1840 was the same chap who returned to England 21 Dec 1850.
Hi I'm hoping someone can point me in the right direction.
I'm trying to trace John Tyler convict # 12354. He was transported on the Mangels to Port Jackson
then onto Norfolk Island in 1840. Then transported on the Duchess of Richmond to VDL in 1844.
He was granted a conditional pardon in 1849. John Tyler then left VDL on board the Sydney Griffiths bound for London on the 21/12 1850.
John of course is a very popular name, and so too is Tyler. Here's two chaps named John TYLER in Tasmania in 1867, and both were victims of crime in the first quarter of that year. Quite possible that either of those chaps could be candidates for the chap granted a conditional pardon 1849.
