In burning a few hours of the midnight oil, I finally tracked down the cause for the death of a cousin of mine. (After a bit of process of elimination between the Wars 1800 - 1899 category and Wikipedia speed reading).
And so of course, not seeing the match listed, I created a category... Wrong move! Already existed, but filed away elsewhere and not fully categorized.
I've already renamed the categories and nested them under the existing category, and put it under the wars category (mentioned above), and added the other appropriate parent categories
Good news for me is that it is one more profile on my Roll of Honour that I don't need to worry about
