Found more info about Glebes from Life in a Medieval Village. Excerpt below. A rectors was a hired priest for a parish to perform the rights and rituals of a private or community church.
Finally, the rector had the income of his "Glebe." the land pertaining to the church which he held as a free man, owing no labor services or servile dues, and which he cultivated as a husbandman. traditionally, the Glebe was twice the normal holding of a villein, though in practice it varied. In 1279 the rector of the Elton church held a virgate, probably distributed in the fields, and, adjacent to the church, ten more acres and a farmstead. surveys of other Ramsey Abby villages list the rector's ;ands in more detail. At Warboys, he held two virgates of land. a house and a yard, and common pasture "in the wood, the marsh, and otherplaces." The rector of Holywell held a virgate, "half a meadow which is called Preistsholm," three acres of meadow distributed in "many places," a tenth of the villagers, meadow, and shares of a pasture and a marsh. In Abbot's Ripton, the rector had a virgate, a parsonage, three houses with tenants, and a common pasture in Westwood."
