hi RL, the problem wiith creating categories as specific as you wish is strictly one of numbers, creating a category for one or two people just isn't needed or wanted.
What you can do is put specific location categories for birth place and marriage & death places, which get outlined in the bio. For example, your profile would have died in say ''Brownville, Orange county, Province of North Carolina'' (imaginary, don't have a clue where he died). There are likely way more people who have BMD in such a specific location.
