I can see a death registered in Belfast for Jemima Kee on 13.1.1949 aged 72. So she died in the Belfast area not in Donegal. Robert died in Belfast on 24.1.1946. There’s a notice about his death in the Northern Whig of 25.1.1946 which gives his address as 13 Derg St, Belfast. He’s in the street directories at that address from at least 1939 onwards. It looks as though the family had moved to live in Belfast sometime before 1939.
