Caldicott was apparently of Cambridgeshire yeoman stock, but he stated in his will that he was born at Esher in Surrey.
Caldicott was returned for East Grinstead on the Sackville interest the following year, when he received two committee appointments, to consider bills against scandalous and unworthy ministers (22 Mar.) and for the relief of creditors (17 April).
Caldicott drew up his will on 5 Apr. 1647, in which he left his son a diamond ring given him by Dorset, and his son-in-law ‘a chest of viols with the arms of my late noble and much honoured lord ... now at my chamber at the sign of The Angel in Cornhill, London’. The will was proved on 9 Oct. following. No later member of the family sat in Parliament.
