The Marlott family acquired by marriage the manor of Muntham in the Sussex parish of Itchingfield, near Horsham, in the fourteenth century, and by 1478 also owned property in New Shoreham.
By the time of his election in 1624, Marlott was an established member of the New Shoreham merchant community.
Marlott appears only once in the surviving records of the 1624 Parliament. In the committee on the continuance of expiring statutes on 12 Apr., he defended the export of barley when prices were low, observing that 20,000 quarters were exported annually from Sussex and Norfolk. However, he also acknowledged his interest in the issue, stating that ‘he hath paid custom for transportation of above 5,000 quarters of barley’.
In 1637 Marlott made a Ship Money payment of £10 on behalf of the constable of Shoreham.
