Clara Simone - I love Clara, and though Simone is not my style I do think this name is pretty.
Eleanor Faye - This one's really elegant but cute at the same time. I love it.
Laurel Tabitha - I love Laurel and Tabitha is nice. I think you definitely have a good sense of how names fit together. This is another pretty one.
Rosalind Emma - I like Emma in the middle spot, but here are some suggestions: Rosalind Charlotte, Rosalind Alice (probably my favorite of these), Rosalind Hazel, Rosalind Eve, Rosalind Willow, Rosalind Kate.
E____ James nn EJ - I'm a fan of nicknames, and I've seen you mention both Ethan and Easton in this spot. Both fit very handsomely.
Percy Robert - It's alright. I do like Percy and though I love Robin I can see why you switched it with Robert because though I haven't heard of any I know Percy can be used for a girl.
Henry Sebastian - I love Henry, and Sebastian is a nice middle but I agree that it doesn't have that super special quality to it. What about: Henry Nathaniel, Henry Owen, Henry Chase, Henry Thomas, Henry Graham, or maybe even Henry Robin?
Caleb Theodore - I really love both of these names and but together this combo is both cute and handsome. Since you're looking though, here are some alternatives: Caleb Thomas (I think this one's actually on my list lol), Caleb Zachary, Caleb Michael, Caleb Daniel, Caleb Ethan, Caleb Lucas, Caleb Mitchell, Caleb Timothy.
Frederick Silas - I'm not huge on either of these names, but I do think it's a nice combo.
