Stagpoole or Stagpool
This name is a variation of the Irish surname Stackpoole ( alt. Stacpoole, Stacpole etc). It is uncommon in Ireland and mostly found in County Clare.
The name is of Norman Irish origin and originates from an area in Pembrokeshire, South Wales known as Stack Poole Heads. The progenitor of the Stackpoole family is believed to have been an adventurer who came to England with William the Conqueror in 1066. A Norman church containing ancestral effigies is still in Pembrokeshire today and the surrounding area is a Heritage Park.
The name probably changed to its current variation when Bartholomew Stagpoole joined the Imperial army (57th Regiment) in January 1848. He was illiterate so unable to spell his name and the army clerk would have written down the name as he heard it.
There have been Stagpoles in USA for hundreds of years however they are not thought to be closely related to the New Zealand branch of the family.
