Character names for a book

Hello, I’m writing a story. Where a family has adopted a girl name Suzetta ‘Zetta’ and I need help with naming the rest of the family. (Father, mother two older sisters, and two younger siblings, (either boy or girl would be helpful. the names that I need can be either old. Classic the world doesn’t hear anymore but might want to, or unusual names that people these days are going with now. Also I need help with Zetta’s middle name as well that can also be the same thing, as well portmanteau or amalgamation names
Can anyone help me out?

 

Their last name is going to be either Sidle, or Ohana (which means family in Hawaii)  while Zetta’s birth last name is Nightingale.  

Thank you very much. 

Turner.
