I knew the date of death of my great-grandfather, but I am making sure I have the complete set of certificates.
He died, aged 37, of laryngeal phthisis in 1902.
I have googled this condition out of curiosity (we have had phthisis before) and found the following:
Tresorie - THE TREATMENT OF PHTHISIS [Treatment Of Pthisis]
It's a really interesting article. What a horrible disease. It seems you rapidly become emaciated and starve to death.
