"C" names

I have a 5 month old boy named Malcolm. We had his first name pick out before he was even thought of. His middle name is a family name and it worked out that his initials are the same as his dad. Im somewhat obsessed with finding a name for our second (yet to be conceived. We're waiting atleast a year so i have time) child. I want the initials to be the same as mine (C.J.) but i dont like many "C" names. Looking for not so common "C" names for boys and girls.

I like Jayne for the middle name for a girl.

I really like Calvin for a boy.

Thanks in advance.
