Plunkett · Pluincéid · Norman
Possibly from blanchet, 'little fair one'. Pale gentry of Meath who stayed Catholic at every cost: St Oliver Plunkett was martyred at Tyburn in 1681, and Joseph Mary Plunkett signed the 1916 Proclamation — marrying in his cell hours before execution.
Power · de Paor · Norman
Le poer — 'the poor man' (a crusader's vow). Norman settlers of Waterford since 1177, so rooted that 'Power' is still the county's most common name — attached equally to whiskey and to hurling.
Prendergast · de Priondargás · Norman-Flemish
From Brontegeest in Flanders. Maurice de Prendergast sailed with the very first landing at Bannow in 1169 — and was praised even by Irish sources as 'a knight who kept his word'.
Purcell · Puirséil · Norman
Pourcel — 'piglet' (a herdsman's name). Butler-allied barons of Loughmoe whose humble piglet-name belied their castles; a Purcell colonel led Confederate cavalry, and the family's hawks appear in Kilkenny's oldest rolls.

These are listed on the atlas under another spelling, but the P form is the one many families carry.
