Given the following context:

The sculptures on the west front at Wells include standing figures, seated figures, half-length angels and narratives in high relief. Many of the figures are life-sized or larger, and together they constitute the finest display of medieval carving in England. The figures and many of the architectural details were painted in bright colours, and the colouring scheme has been deduced from flakes of paint still adhering to some surfaces. The sculptures occupy nine architectural zones stretching horizontally across the entire west front and around the sides and the eastern returns of the towers which extend beyond the aisles. The strongly projecting buttresses have tiers of niches which contain many of the largest figures. Other large figures, including that of Christ, occupy the gable. A single figure stands in one of two later niches high on the northern tower.
In 1851 the archaeologist Charles Robert Cockerell published his analysis of the iconography, numbering the nine sculptural divisions from the lowest to the highest. He defined the theme as "a calendar for unlearned men" illustrating the doctrines and history of the Christian faith, its introduction to Britain and its protection by princes and bishops. He likens the arrangement and iconography to the Te Deum.According to Cockerell, the side of the façade that is to the south of the central door is the more sacred and the scheme is divided accordingly. The lowest range of niches each contained a standing figure, of which all but four figures on the west front, two on each side, have been destroyed. More have survived on the northern and eastern sides of the north tower. Cockerell speculates that those to the south of the portal represented prophets and patriarchs of the Old Testament while those to the north represented early missionaries to Britain, of which Augustine of Canterbury, St Birinus, and Benedict Biscop are identifiable by their attributes. In the second zone, above each pair of standing figures, is a quatrefoil containing a half-length angel...

answer the following question:

What are the names of the missionaries of Britain that the sculptures in the north represent and are identifiable by their attributes?? 

Augustine of Canterbury
