Irish Boys names

Kristin
My husband and I took a 10 year anniversary trip to Ireland and came back with the surprise souvenir of a lifetime. We do have some options but just looking for other ideas. Sisters are Aislinn and Abby. (Aidan not an option bc new nephew is Aidan) I'm big into meanings of names Aislinn (pronounced Ashlyn means dream, inspiration ) Abby means father's joy. Feel free to share ideas. Thanks!
