I have today received the death certificate of my gg uncle who died in 1898 aged 26 years on the census it referred to him as an imbecile, and in his fathers will provision was made for him after his parents death, I there presume he was of special needs. On his death certificate however it says he died of Chronic Brights Discease could anyone tell me what this is, I have tried to google it but it has made me even more confused.
Many thanks
Susan
