Ippollitts or St Ippolyts, is a place name which is very prone to being mispelt and the village on modern maps (St. Ippollitts) is spelt differently to the dedication of the church (St. Ippolyts).  The following place names from the 1881 census almost certainly all refer to it:

Iplits | Ipolits | Ipollitts | Ipollyts | Ipolytes | Ipolyts | Ippatyts | Ipplits | Ipployts | Ipplyts | Ippolett | Ippoletts | Ippolits | Ippolitss | Ippolits | Ippolitss | Ippolitts | Ippollit | Ippollits | Ippollitts | Ippollyts | Ippollytts | Ippololits | Ippolts | Ippolytis | Ippolyts | Ippolytts | Ippoplitts

IPPOLITTS, a parish in the hundred of Hitchin and Pirton, county of Hertford, 1½ mile (S.E by S.) from Hitchin, containing 671 inhabitants. The living is a vicarage, united with Great Wymondley in 1685, in the archdeaconary of Huntingdon, and diocese of Lincoln, rated in the king's books at £11. The church, dedicated to St. Hippolytus, has at the western end a square tower, embattled, and surmounted by a short spire: adjoining the church-yard are two almshouses, endowedby a person unknown.

Who was St Ippolyts? We have a choice of known facts and of legend. St. Hippolytus, a Roman theologian, who died about 236 A.D., produced a valuable study of the Liturgy and worship of the Apostolic Church. The third Eucharistic Prayer in the Alternative Service Book widely used today is believed to be based on a prayer written by St. Hippolytus.  There are  also legends of a St. Hippolytus, Bishop of Ponto, who was dragged to death by wild horses. This saint may also have been the younger soldier who guarded St. Lawrence before he was martyred, and who was converted by Lawrence's fortitude. From the name Hippolytus comes the connection with horses (hippos = horse in Greek). Another story is that Hippolytus was no Roman saint but a man known to be skilled in taming colts and in treating sick horses. Thus St. Ippolyts Church became known as a place to which sick horses were brought to be blessed. In various parts of the church representation of horses can be seen - as on the Lectern.
