In the roll there are columns for the proprietor, the tenant and the occupier.
Sometimes the proprietor is the occupier. Sometimes, as in your case, the proprietor has rented the property to a tenant who lives there (the occupier). Sometimes the proprietor has rented the property to a tenant who has someone else occupy the property. For example a tenant farmer might be tenant and occupier of a farmhouse, but only tenant of a farm worker's cottage, the farm worker being the occupier.
