Granborough was once part of the Manor of Winslow. A windmill stood on the hill in a field still called Mill Knob.

An older resident recalls the village in times past:
Granborough in the days of my youth was a very friendly village, full of people of all ages, some very old. One thing which remains in my mind is the old ladies sitting in the doorways of their cottages, a shawl around them to keep warm and a pillow on their knees, making lace, without spectacles or any other aid.
Most of the present day inhabitants work outside the village, except those who work on farms. We once had a blacksmith, a wheelwright and undertaker, a coal merchant, baker, builder, post office and general store.
I remember that at one time the house known as Granborough Lodge, then the Vicarage, was supposed to be haunted by a vicar who died at Scarborough by drowning. Although I lived there for a number of years I never saw him.
During the war there was a day of fear and excitement when an American plane dropped a bomb in Church Lane which demolished the house of Mr W. Newman, our greengrocer, and damaged a few others.
There are a very few of the old families left now, but lots of newcomers, who we are pleased to say are very friendly and helpful, both in the church and in social life.
