I noticed the other day that I like E names and also names with F sound or other soft sounds for girls. DH vetoes them all.
I have had a crush on Ethel for the longest time. Elizabeth is on our list. I really like Evelyn and Eleanor/Elinor as well, I like but wouldn't use Emily and Emma. Fiona, Phoebe, Daphne, Sophia. Hadassah- to which DH asked "What is wrong with you?!" Millicent, Susannah, Samantha, Josephine Isabella, GP of Shenandoah, Charlotte have all been on our list before.
Maybe that's why Margaret doesn't quite feel right? And possibly why Katherine is the only K name on our list...and even then I prefer it with a C because it looks softer. I've liked ones with hard sounds too like Margaret, Grace and Rebekah but this might explain things a bit better to myself.
Is there a certain sound you're drawn to?
