I'm sure we all still think very fondly of Nat.
I also wondered about poor Uncle John too Carole. I have a d/c for ancestor of my OH who died in 1854 and her cause of death was "Asiatic Cholera 23 hours", but I'm not sure if they were always so specific. (she left 8 children and her husband remarried exactly eight weeks to the day after her death

).
I'm not sure John died of Cholera as I think it strikes a lot quicker as per my example. Sounds dreadful doesn't it especially with the lack of 'facilities' available at the time.

I was considering buying Mary's (Nat's mother) d/c, but although we know her date of burial:
29 Oct 1847, St Anne, Soho, Mary Ward, Richmond Buildings, age 50
there are two possible deaths:
Both deaths Dec 1/4 1847,
Ward Mary,
either St Pancras 1/328
OR Marylebone 1/152

Looking at where the deaths are registered if someone can narrow down which would be the most likely, I
may (have to) buy it.

There is also Granny Shepard's death, but due to her age I expect her cause of death will be age related and maybe vague so I'm not sure I would bother to purchase that:
20th Nov 1851
Parish of St Pancras
Mary Shepard buried, age 80,
abode: Infirmary
