I feel like a lot of parents of multiples (especially higher-order multiples) do the A/B/C/etc thing. I kind of wonder if, for the triplets, they had the same names picked out so that no matter the order of the genders, it was the same, since all the names are unisex. I'm not sure whether AJ was short for anything or not.
One of the
Ashlyn's (twin to
Hannah) is a student in my 4th grade class that I intern in. The other
Ashlyn (twin to
Brooklyn), I don't actually know, but one of the admins at the school gave birth to her just this week. If you look at popularity data,
Ashlyn has been hovering around the 200-mark for a couple decades, so it's pretty popular.
