Thank you daisynook

It’s hard isn’t it - or at least I think so.
I know I am digressing but is this right?
Marriage 1947 Kensington
James Reilly and Mary Kate Barton
Do you have a copy of the certificate? It looks likely that M K’s sister, Anastatia married at the same time.
Birth
Mary Kate Barton 1923 Kilkenny
Death
Mary Kate Reilly 2006 Brent. Her birthdate 14th August 1923. So that looks good.
I can’t see a death for James Reilly in 1973 which would fit with the information you have given.
Would you give the death record details you have please? Is the year of birth shown as 1928?
