I was going to comment, before I got to the end of your post and saw your question, that I actually like the way you do
BAs alphabetically. It's a good way to see variations in combos and spellings and also get a good idea of what names are popular.
I can see there will be a lot of Zacs in British schools in a few years time!
And I've never seen a family with nine sibs in a BA before!
