Ashley, I love Irish names too. My girl name (before I had DD) was Fiona but when I got pregnant it fell off the top of my list for some reason. DD was nearly named Saoirse though. ;) This time around there are a few Irish and Scottish names on both girl/boy lists but the top contenders so far aren't Irish again, so we will see.
I am a big fan of longish names that can be shortened into a cute nickname, probably because I couldn't do anything with my own growing up. :p DD was named Wilhelmina but she often goes by Willa or Mina, or Mina-mina as she often calls herself. Her paternal grandmother is Wilma and she was named for her father William so when Wilhelmina popped into my brain (and showed up in a dream) we thought it was a good fit. Her middle name is Elizabeth after my mother's cousin who was a little like a second mother to me when I was very young. Her second middle name is my last name, and her last time is the same as my husband's.
This time around I'm looking towards family-related names again and my favourite so far is Juniper with a short form of June. June was my maternal grandmother's name. My husband isn't a fan of Juniper though. :( My paternal grandmother was Muriel so that is another contender but it tends to sound really granny-ish in my mind.
For a boy, our top name right now is Peregrine with a short form of Peri/Perry or Perrin. I'm also debating Lindsay for a boy (don't like it for a girl) as a middle name since that was my maternal grandmother's maiden name/Scottish clan. We will likely use the same FirstName MiddleName MyLastName HusbandsLastName format this time around too.
