I am about to start a new character. I am wondering if my kins from my current character will still show up in my kin list.
Also wondering about when I kin someone if the character name shows or my account username. Thanks in advance

Nope, they have different kin lists. There is a presentation name that you can set in your buddy list and that is how they will see you when they kin you. If you do not set that name than they see your character name.
