Well, yes, Bree and Pamela, you both have points. It's just that, as a Baptist, I am very aware of just how fragmented Baptists are. (The last time I checked, there were 21 different Baptists conventions just in Canada, and something over 200 in the USA. And that's not counting all the independent Baptist churches that aren't part of any convention.) I really didn't want to have to go to all the work of breaking people up into categories that fine. But, on the other hand, the finer the categories we use, the more likely it is that finding two people in the same category means that they have a family connection, too.
