Parish in the north of the Isle of Man, extending from the northern plain into the Sulby valley.

Lezayre formed part of Ayre Sheading with Andreas and Bride. The parish stretched inland from the district around Ramsey and contained the valley of the Sulby, one of the largest river systems on the Island.

The Sulby river was important enough for a new bridge to be specifically included in the eighteenth-century programme of bridge building. The Act of Tynwald of 1739, which levied a penny annually on inhabitants between sixteen and sixty for bridge repairs, listed a bridge over the Sulby in Lezayre as the first of the new bridges to be constructed.

Milntown, the principal seat of the Christian family, lay in the parish. The family produced generations of Deemsters and other officers, and William Christian, Illiam Dhone, was a younger son of Deemster Ewan Christian of Milntown.

The parish was predominantly agricultural. Its lower ground formed part of the fertile northern plain, while the upper Sulby valley ran into the central hills. The road through the valley provided one of the principal routes between Ramsey and the west.

Sulby was also a fair centre. Robertson's eighteenth-century list records two fairs there in June.
