The name Petsoe is used frequently in the local area, with other local hamlets being called Petsoe End and Petsoe Lodge.
Petsoe was formerly a separate parish from Emberton, but was annexed to the latter parish in 1650 for ecclesiastical purposes. There was another parish nearby, called Ekeney which was also annexed at the same time, though nothing reamins of Ekeney today.
Today nothing remains of Petsoe church, though the landmarkings showing where it once stood are still discernable.
