The History and Antiquities of London, Westminster, Southwark, and Parts Adjacent, vol. 2Allen, Thomas
The Common Serjeant.
His duty is to attend the lord mayor and court of aldermen on court days, and to be in council with them on all occasions, within and without the precincts or liberties of the city. He was to take care of the orphan's estates, either by taking accounts of them, or to sign their indentures, before their passing the lord mayor and court of aldermen. And likewise to let, set, and manage the orphans' estates, according to his judgment, to their best advantage. It is also a part of his duty to attend the meetings of the livery at large when assembled in the common hall, where he dictates the names of the persons in nomination to the common cryer, except in cases of election of members of parliament. He is also to attend the courts of aldermen and common council. The present common-serjeant is Thomas Denman, esq.
 This portion of his duty has now become obsolete.
