Michael Barnes dies and is succeeded by his son who immediately sets about expanding the business by hiring an articled clerk by the name of Ambrose Glover. The practice moves to Church Street in Reigate.
George Morrison, a solicitor from Newcastle, moves to Reigate and starts his own practice at 46 High Street in Reigate. The two practices merge.
As the new partners are admitted, the name of the firm changes to Morrison & Nightingale, then Morrison, Nightingale & Hewitt and then Morrison, Hewitt & Harris. During the 1800s, the firm manages the Priory Estates which consist of the Priories of Reigate, Nutfield, Limpsfield, Tadworth and Burstow.
