Hi Karen,
Thanks for your message about William Budgen. I did a search on Ancestry and found a family tree under Wallis which also has "my" Budgen's on. There are two Williams also, one born in 1806, and one in 1848. I don't know if it is the same William though. I have contacted the owner of the tree for more info.

By the way, our family lived in Australia for a while - Tasmania 1960-62, and Sydney 1978-80. Last visit 1990, although my brother was there this year. Still have lots of friends in Oz, and fond memories. My mother also had a convict ancestor, on James Budgen's wife's side of the family!
Look forward to hearing from you.
Regards,
Sue
