I am not sure where the Winslow family originated. Winslow, Buckinghamshire is less than 20 km. from Bicester, Oxfordshire, which seems to be near many of the families which interacted with the Winslow family, except for the Crouchmans which were of Cambridgeshire, but as a London Grocer John would be interacting with many diverse families. If that is where the family originated, they did not hold the manor in the village of Winslow, which was held by the Abbey of the Church of St. Alban.
