z baby names for boy

My boyfriends name is zackiel, we were going to name the baby after him and his nick name be zeek. But I've changed my mind and have stuck with zeek for just his nick name which is actually going to be mainly what everyone calls him. But I need a real name for him and I've came up with za'ky only problem is I have a friend and her sons name is mehki and I know a girl her daughters name is zakyiah. I don't want to steal baby names as there's a million to make up or chose from but can someone please help me out. I'm stuck. And I like za'ky im just 50/50 with it like not in love with it.
