I think only people with an Irish heritage understand Niamh is pronounced Neve.

I wanted all my kids to have Irish names - hence DD being Tara and DS2 is Liam, we had Cale originally for DS1 but then DH went off it and I couldn't find another short Irish name we liked so went for Rhys instead (which is Welsh) but it is still Celtic but his middle name is Patrick so the Irish name carries on in his middle name.

Irish names can be so hard as most people get confused by the pronounciation, but I love tham anyway.
