Despite an increasing number of fully accredited Irish citizens with unusual surnames — such as Olympic badminton player Nhat Nguyen, world class sprinter Rhasidat Adeleke, and hip hop artist Denise Chaila — it’s a safe bet that any round-up of common family names here will produce the usual suspects: Murphy, Ryan, Walsh, Kelly and McCarthy, for starters. This means that your average Irish person most certainly has a namesake. Indeed, more like hundreds or even thousands of them.
