Need help with sibling names?

Okay, so I'm not pregnant or anything ( my husband and I already have 2 kids) but I want to think of some names for my future kids. Our 3 year old daughter is named Felicia Sadie and our 1 month daughter is Trinity Karah. We were thinking of for girl Camilla or Camille. Would Felicia, Trinity, and Camilla sound good. For bys we were thinking of Bryce Matthew ( We thought Felicia would be a boy so that was our choice, but she was a girl) or Kayson Bryce. Could you maybe help with middle names for the girls. Thanks.
