The exact origin of the name Datchelor is uncertain and has not been conclusively documented in accessible public records. The most probable explanation is that it derives from a surname—either a property owner, landlord, or early resident who lived in or owned land in the area during the medieval or early modern period. The surname Datchelor (also spelled Datcheler, Datcher, or Datceller in historical documents) appears sporadically in English records dating back to the 16th and 17th centuries, though no specific individual has been definitively linked to this particular Southwark street.
The street itself appears to have been formally named or recorded during the 19th century as the Camberwell area underwent intensive residential development. By the time Datchelor Place is documented in Victorian-era maps and trade directories, the name was already established. Without access to local property deeds, parish records, or estate papers, the identity of the original Datchelor remains lost. The street name represents one of thousands of urban place names whose human origin has survived into the modern era, but whose story has not.
