CASHIO, or CASHIOBURY, a hamlet in the parish
of WATFORD, hundred of CASHIO, or liberty of ST-ALBANS,
county of HERTFORD, l mile (N.W.) from Watford,
containing 789 inhabitants. In the time of the
early Britons this was a place of importance, having
been the seat of Cassibelaunus, King of the Cassii, from
whom it derived its name; the Saxon kings of Mercia
also made it their residence, and Offa included it in the
possessions that he gave to the monastery^of St. Albans,
and called it Albaneston, which was again changed by
the Normans into Caisho, since converted into Cashio.
Edward IV. constituted it a liberty, and it continued
annexed to the crown from the period of the dissolution
until James I. granted the whole liberty of the monastery
of St. Albans to Robert Whitmore, Esq., and John
Eldred, Gent.
