Hello Ian,
Welcome. Do you know about John Tawell, who was executed for murder in !845?
There is masses of information on line about him which you can find online by using a search site such as Google or Yahoo.
If you think he might be related, contact me by PM when you have made the necessary number of posts - I have notes which might be helpful, from a thread I posted on another forum a couple of years ago and could perhaps point you to some references.
Roger
