Orlagh was in the top 100? You must be Irish. (My mother is from Clonakilty.)
I knew an
Orla once with the personality of a tank. I had never heard of the name before so it's hard for me to separate the two. But that's my limitation. It certainly is a beautiful sounding name and has a lovely meaning. Do you like the name
Aurelia? It's grown on me lately. although I can certainly understand if you want an authentically Irish name. (I've always thought
Oonagh is pretty neat.)
As for the combination,
Orlagh Morgan Isabelle, I love the name
Isabelle, but I only like
Morgan for a boy. Besides,
Orlagh Morgan has too much "or" sound together. How about:
Orlagh Maeve IsabelleOrlagh Siobhan IsabelleOrlagh Vivien Isabelle
