The name derives from the Old Scandinavian 'Kariby' or "village of a man named Kari," and first appears in 1199 as Careby.[3] The placename suffix, "by", is common in this part of the country, being part of the Danelaw.[citation needed]
Although very small, Careby is the largest settlement in the parish. An old manor house, successor to the rather grander home of the Hatcher family who once owned the parish, is down a small lane leading away from the railway, which also includes the 19th century rectory, now in private hands.[citation needed][original research?]
The village school was opened in 1869, and closed before 1970. The building, to the west of the railway line, is now a private home.[citation needed]
During the Second World War the village played host to children from Sheffield who attended a working farm camp to help with the harvest. They were accommodated in the village hall.[6]
