Trying to help my sister name her child but she likes ghetto names

I really like the names Ashlynn Nicole, Jaylynn Michelle, and Alannah Nicole. I don't think they even sound ghetto but are so pretty. For the boy names, I love the name Jayson Un'dreus (I just love the name Jayson). I think a lot of the names you have picked out are really cute. How about Jalen if it's a boy too?
