Why The Letter J Is So Rare In Irish Names

Before jumping into the names themselves, it helps to understand why J-names are uncommon in Irish culture to begin with.
The traditional Irish alphabet has only 18 letters. The letters J, K, Q, V, W, X, and Y were simply not part of it. Because of this, the Irish language never developed native J sounds. When biblical and European names containing J arrived in Ireland, mainly through Christian missionaries and later through the Anglo-Norman invasion of 1169, the Irish language adapted them by replacing the J sound with the S or SH sound instead.
So John became Seán. James became Séamus. Joanna became Siobhán. These Gaelic versions of foreign names became deeply embedded in Irish culture and are now considered classic Irish names in their own right.
This also means that most Irish names starting with J are either anglicized versions of Gaelic names, names brought over through English or Norman influence, or modern names adopted from other cultures. That is not a bad thing. It actually gives J-names in Ireland a layered, interesting history.
