Plz Help With Our 4th Childs' Name

On behalf of my friend:

First and middle name ideas for our fourth child plz. Not sure what the gender is yet…

Our first son is named Reborn [name_m]Charles[/name_m]-[name_f]Edie[/name_f], in honor of my brother. Our second son is named [name_m]Calm[/name_m] [name_m]Tiger[/name_m], and our daughter is named [name_f]Evening[/name_f]-[name_f]Lily[/name_f] Tibet…

Any suggestions that you can think of will be extremely helpful! Thanks in advance x
