Carlton is shown in the Bacon's Popular Atlas of the British Isles (Cambridgeshire) 1904 shown below.

Interesting features shown are:

• The green lanes to Weston Green and Willingham Green from the church are not distinguished from other roads.
• Nawney (Norney) Farm is still shown, and appear to be accessed from the North.
• Towards the top left is written Carlton Oak - does anyone know why?
• Carlton is spelt using the modern spelling, but Carleton Green still has the extra "e".
