1) The holding and maintaining of a house.
The OED has several other shades of meaning but no examples of the word earlier than the 1380s. The surname ‘Household’ is therefore of interest although it did not survive: n.d. Petro Hushald de Seleby ... toftum Walterus Husold, quondam pater meus
1297 Carta Petri Hushald de Seleby
1312 Petrus Housald de uno messuagio ... in Seleby. The surname may have derived from a place-name or given its name to one: 1463 ‘three roods lay in Howshald’, Drax.
