My grandmother was Sarah Betts born about 1845 to William and Sarah Mac Farlane Betts- both born in Scotland and came to Stellarton- he to work in the mines.
Not sure where you live, but there is a new genealogy site in Nova Scotia from the Archives- they have quite a few names of births, deaths and marriages online and are gradually adding I understand. The births so far are years 1864-1877; Marriages- 1864-1930; and Deaths 1864-1877 and 1908-1955.
I have found James W. Betts and Annie Vaux's marriage records for April 19, 1854; and Annie Vaux betts" death certificate for July 13, 1921.There is a death of a James W. Betts but it doesn't seem to be the correct one- and hers shows her 82 years of age and widowed. Perhaps he died before 1908. This site can be found at https://www.novascotiagenealogy.com/
It is quite an interesting site and becomes very addicting! I understand there were three Betts brothers came to Stellarton from England- so wonder if there was a connection between my Sarah and James W.???
