Emma-Kate, Serena-Claire, and Lily-Katherine (or Lily-Kate) feel the easiest to get to stick as a double barrel, but I like Lily-Serena and Serena-Katherine/Serena-Lily a lot. [name_f][/name_f] There was a berry on here years ago who had a daughter named [name_f]Serena[/name_f] [name_f]Isabel[/name_f] [name_f]Joy[/name_f], I think Serena-Joy would be a great double barrel too.
[name_f][/name_f]Good luck!
