Irish baby boy names.  Blue-eyed red-haired baby with bubbles.

I went through the process of choosing an Irish baby boy name when we named my third son Aiden.  Derived from the name of a 7th century Irish bishop - Aodhan - it basically means "fire" or "fiery one," reflecting the qualities of passion and strength.  A good choice on our part, if I do say so myself :-)

Anyway, I look forward to sharing some of our favorite Irish baby boy names with you and providing links to many more.  Let's begin!

Choosing an Irish Baby Boy Name

One place to start when choosing an Irish baby boy name is to answer a few questions for yourself and your co-parent.  What are the qualities you value and want to instill in your little one?  What aspects of Irish culture or history do you want to honor and commemorate in your family history?  Which Irish baby boy name sounds like it would be fun to say over and over again for many, many years? :-)

Please keep in mind - names often have very complex histories and a variety of different meanings.  The names below are my best summary of what I have learned about choosing an Irish baby boy name, but I make no claim that they are all 100% correct (or even 100% Irish, although they all have ties to Ireland). 

With that in mind, here are some ideas to get you started.
