Julie - I add those categories for the benefit of those who do see some use in them. Where possible, I like to know where my family lie buried, if they were buried, or what was the disposition of their cremains if cremated -- especially after learning that some cremains were never given to the families and to this day reside in some funeral parlour, or were mass interred in a common hole in the ground, or simply dumped in a garbage skip; or the family was only given part of the cremains (the small urns usually seen in movies and tv shows would barely hold a small animal, let alone the 6ft, 180-200lb adult male of the story); or the supposed cremains included handles and other objects not of their loved one.
Admittedly, it would make more sense to my mind to at least use a country, but I'm not a Cemeterist and have no idea why the Project has chosen to categorise as they do.
I have noted more than one suicide in a biography, but draw the line at adding such a category, because I see no benefit in it.
I also understand this can be a sensitive subject for many, and so apologise if my blunt words above cause distress, or offense. I do not mean them to.
