Elisabeth Kate- Very pretty but plain.
Cassandra Vivienne- Lovely, but a mouthful. Cassia Vivienne, perhaps?
Charlotte Lorraine- Pretty and vintage!
Catalina Lucy- I like this a lot! So sweet.
Rosalie ???????? (suggestions?)- Rosalie Pearl, Rosalie Odette, Rosalie Regina, Rosalie Iris, Rosalie Georgia
Anneliese Scarlett- Hmm, I don't love how the ending of Anneliese blends into Scarlett. Sounds like Anna Lee Scarlett. Annika Scarlett or Anneliese Ruby?
Mackinley Alice- I kind of like Mackinley Alice. Alice Mackinley would be even better, though.
Abbigail Mackenna- I prefer the spelling Abigail- a girl named Abbigail will probably get sick of saying, "No, Abbigail with 2 Bs!" The combo itself is okay, but not spectacular.
Elisabeth Kate - classic
Cassandra Vivienne - I agree that this is a little long-- what about Cassandra Vale?
Charlotte Lorraine - very nice-- this is my favorite on your list
Catalina Lucy-- for some reason, this is hard to say, maybe Catalina Mae, Catalina Drew instead?
Rosalie - Rosalie Faith, Rosalie Beth, Rosalie Grace, Rosalie Merit, Rosalie Thais
Anneliese Scarlett-- I agree that this kind of runs together-- what about Anneliese Marion, Anna Scarlett, Nadia Scarlett, or Annabel Scarlett?
Abbigail Mackenna-- nms-- I dislike the double B in Abigail (not sure if this was just a typo)-- what about Abigail Marina or Abigail Marjorie instead?
Annabel Grace-- nice and sweet
