There are some Irish people with Afros (Eg. Andre the Giant), but I guess they are just Negroidic Caucasoids.

According to Western scholars Caucasians can have White to Black skin colour, any nose type barring the extremely wide ones, straight to curly hair, and even mongoloid-like eyes.

This would mean there is NO Negroid influence in Ireland, they just happen to be Negro-like Caucasoids. =D

It is agreed that humans came from Africa, therefore the Irish must have Negroid features. The Cro-Magnoid people that left from Africa to Europe, were most likely black skinned (unless melenin levels decreased whenin Africa), and they had Negroid features. This can explain why such features might be found in Europeans. An example being the narrow and long noses Europeans. There are East African with such noses to, therefore it proves that Europeans have retained some of the Negroid features of the early-Humans. =D
