The existence of an earlier building to the one now standing may be inferred from the beautiful Norman font found within the church and the existence of other artifacts of the same age.
These were found buried in debris beneath the church in the 19th Century.
The font in particular was found in three fragments and work was done to repair it.
This font can be found at the West End of the Church today and has given its name to a particular style of font known as the "Aylesbury Fonts".
These fonts are normally dated late in the 12th Century around the years 1170 to 1190.

The early ecclesiastical history of Aylesbury is confusing and difficult to unravel.
The Church was a Prebend in Lincoln Cathedral.
It will be seen that the Prebendary of Aylesbury was attached to the See of Lincoln as early as 1092.
An early account states "It is said that a Bishop of Lincoln, desired by the Pope, give the Personage of Aylesbury to a stranger, a kinsman of his, found means to make it a Prebend, and to incorporate it to Lincoln Church."
So in the reign of Edward III Aylesbury Church was part of the Deanery of Lincoln, and a separate stall in that Cathedral was set aside for the Dean.

During excavation work in recent years a 12th-century cloister and a conduit pipe were identified.
