Hello
I guess you have found the Thomas Moses who was born June 1752 in Newcastle and who emigrated to Norway 1768. He would only be 16 years at the time. Thomas never married in Norway. He died 1822
The probate of Thomas lists 5 sisters in Newcastle (in this order):
Ann Wardle, listing 5 children
Mary Drummond, listing 4 children
Elizabeth Weatherby, listing 2 children
Jane Richarby, listing 2 children
Margereth Cook, listing 5 children
and finally, living in northern Norway
Ann Thomina, no children mentioned
I'm not sure the will/probate mentions any John, but then I haven't studied it too well. Took a few photos of pages who. I thought, could contribute to deciding which family this is.
"Old" Thomas should be "Old" Johns brother, originating from Berwick upon Tweed, according to what is part of Kristiansund's history.
As to long established links, I do hope there will be a new ferry-route soon!
