What are some different Irish baby boy names?

I recently have taken an interest to Irish names. It is where my grandparents are from and I want my child to have a different name. I like the name Liam but I find it too common. I want a name like Declan, Caelan, Calum (this is the Irish spelling), Finley or Lachlan. Are there any names you like or know of like this?
