Hello Marge

I hope you don't mind me responding to your posting but I am also tracing the same family tree. My gg grandfather was Joseph Casson, brother to Isabella Christian nee Casson. I have a copy of immigration papers belonging to Isabella's daughter, Isabella Watts nee Christian, from 1927 that you may be interested in. I mostly have information about the Casson/Pearce branch but this may prove useful for you.

Kind regards, Lisa
