DD#1's middle name is Marie, which would work with Delaney. DD#2's middle name is Kathleen, which would work with Delaney or Mackenzie (very irish sounding).
It is difficult. DD#1 was easy, but I decided to name DD#2 Erin and did not like any of the middle name options I came up with--Elizabeth, Nicole, etc. I teach at a HS so I stopped every single Erin I found for 2 weeks until I ran into Erin Casey, who told me her middle name is Kathleen--Erin Kathleen McConnell, you can't get much more Irish than that!
