The village is supposedly named after a Saxon chieftain, named Wikki, but there is evidence of earlier settlement. Bronze Age double-ditch enclosures and middle Bronze Age pottery were identified in the 1960s, and early Bronze Age items, such as an axe and spearhead, have been found in the Thames. Later settlement evidence is more extensive: Iron Age and Roman presence is indicated by trackways, various buildings (enclosures, farms and villas), burials (cremation and inhumation), and pottery and coins. There is also evidence of possible Frankish settlement: a 5th-century grave that contained high-status Frankish objects. This early habitation was first revealed in the 1890s, in the first ever use of cropmarks to discern archaeological remains. In 2016, on land owned by Sylva Foundation, an Anglo-Saxon building was excavated by Oxford University School of Archaeology.
