To the east of Kellaways, there is evidence of occupation from the Iron Age in the form of a banjo settlement (a feature which typically dates from 400-100 BC). This settlement consists of three adjoining, sub-rectangular, banked enclosures, the northernmost of which may be a banjo enclosure. A banjo enclosure is named because it comprises a circular area bounded on all sides by a ditch and outer bank. It has a long entrance track leading to it from one direction. Hence the feature looks like a banjo.

There is some indication of Roman occupation across Langley Burrell and Kellaways, suggested by various finds, including the discovery of a rotary quern (used to grind grain) northeast of St Peter's church (south of Stein Brook) and Romano-British pottery finds southeast of Kellaways Farm. However, the strongest indication of Roman occupation in the parish lies in the area around Bird's Marsh, where evaluation trenches, geophysical and LiDAR survey have revealed a probable native Romano-British farmstead south of the woodland, consisting of a co-axial settlement with enclosure and drainage ditches, and a possible round house. Local coarseware pottery from the site date principally to the later 1st and 3rd centuries AD.
