Frances,

I am close to giving up on the connection I originally harboured i.e., that Henry and Ann's son Thomas is linked to my family. I did see the census entry for Thomas at Sulby Bridge and I too thought he was probably Henry and Ann's son, but in the 1871 Arbory census a Thomas Cubbon and Catherine ?nee Kewley are living very close to my ggrandparents on Malew Rd-they are in fact the next entry, though I'm not sure what that means it seemed a more likely couple.
That's where I sit right now. I don't know that Henry & Ann Cubbon aren't connected to my family in some way but at present I have nothing.
I will definitely be researching wills in the coming weeks.
Any thoughts/impressions/suggestions/input gratefully received.

Thank you

Ann
