IF it is a boy, it will probably be Theodore Edward, but he will be called Theo. (though I could see calling him Teddy Bear on occasion to)
I like Everly, it is pretty
As for Harrison, my only thing - and it is just me - I like to be able to shorten a name if I want, and Harrison is really only shortened to Harry I think. Some people like names that cannot be shortened. My parents picked my sister's name - Chantelle - for that very reason, nevertheless, she now goes by Telly (but we refuse to call her that! LOL)
Kinder, I wish I felt as definite as you! I have no clear idea of the gender. Two of my cousins both have daughters named Carly (one is Karly) they are both on my dad's side of the family. It is a cute name though!
Alliteration with names can be cute or not - my dad and his brothers are Tim, Tom, and Ted. Their sisters didn't get the memo - Cristina and Penny - my Uncle Tim's sons are Jason and Jeremy. My aunt Cris named her son Thomas Timothy after her brothers . . . my mom's sister named her girls Brittany, Brandi, and Brianna. We chose to NOT name DS Brandon because we felt there were enough BR- names in the family! - do whatever works for you though, if you find a name you love that starts with K; but don't discount a name you love just because it doesn't.
