The Peppards were contemporaries of the De Angulo but not related from my research. Both families built castles and were” aristocratic mercenaries “, as the Historian Curtis called them.
Peppards were English , De Angulo were Welsh Norman’s . They were from Angle in Pembrokeshire, and founded MacCostelloe, Nangle, Nagle, Jordan, MacWaltrin( Waldron), macPhilbin, MacPhillips septs, to name a few!
