Personally, I think Connor Kirtley sounds lovely. I even asked the opinion of my resident teen, and she said it sounds like a pop star name or an actor... So it has the youth seal of approval too :-)
Connor is an Irish name and it means 'lover of Wolves' or 'lover of hounds' so he's already a dog lover, which is always a plus!
I just looked at the traits of boys with the name Connor and I think he's onto a winner! Apparently people with the name are excellent at learning and understanding and have a deep desire to express themselves, often in writing, acting or singing... So he really does have a chance of being an actor or pop star.
Go for the name that you really like, in this case I think it's a great fit but it is such an important decision that it is one that really only you and your husband can make.
I hope the rest of your pregnancy goes well and that your baby boy is healthy and happy, let me know your final name decision.
