Indeed, yes the 1875 marriage in Blackpool was to Ada Cadman (I have a photo of her if anyone is interested). Their children and grandchildren are well known; again I have info on that.
Religion: Not sure which, if any, church they attended in BallyDonelly, but not Catholic - there was rather strong anti-Catholic sentiment from what I can tell. Son William John attended protestant church in NZ.
Here is what is making me connect Stuart Boyd Connolly to Charles:
1875 marriage cert listed father as Charles, a Farmer.
Family oral history indicated he was born in Ireland, and there was a brother "John" who moved to Australasia.
AT this point, we had no connection to BAllyDonnelly. I think I found 25+ Charles Connolly in Griffiths valuation at that time.
I am great grandson of Stuart Boyd Connolly; In 2024 I had many DNA matches to NZ descendants of William John Conelly .
a 1902 document of NZ settlers listed William John Conelly and included:
name of his brother "Stewart", businessman of Manchester
place and year of birth in Ireland as BallyDonelly, Antrim 1844.
Fresh search of Griffiths showed the 1 Charles COnnolly .
