But what do you call Belladonna's new baby brother?

Here are some sibling groupings. I tried to avoid obvious, cutesy combinations (including alliterative names). Instead, I focused on keeping balance in the groupings. Imagine having a family of siblings named Joe, Sue, Anabella, and Frank--who feels like the outcast? However, if we alter the group for balance, we could end up with Joe, Sue, Ann, and Frank; or Josiah, Suzette, Anabella, and Francis. It's all about harmony. So, try these groupings on for size, and while you may not choose all the names in a group, they are good examples of how to create harmony among the family's names without resorting to naming everyone with the same first initial.
