Hello Denise
Cannell is a Manx name and at the moment I'm trying to trace William Charles, Elizabeth Todd's husband, and his family but they're proving a bit elusive. I think his father died and his mother re-married but I'm still checking.
Are you in Australia or did the family come back to England?
Good to hear from you. If there's any other info I have that you'd be interested in please let me know
Regards
Barbara
