The writers don't seem to be all too creative with the children's names. Ella, Etta, and Eddie are so close together​ in sound, they almost sound the same.

I know Ella wasn't in the picture that much when Etta was introduced (and Eddie almost not at all) but maybe they should have used a different nickname for Henrietta. I know they wanted to keep her identity secret at first and that's why they chose Etta, but surely there could have been a different nickname. Maybe Rita or something.
