Morice’s grandfather, who acquired the manor of Chipping Ongar in 1542 and sat for Downton in 1547, was an early convert to Protestantism.
On the death of his first wife’s father in 1607, Morice succeeded under entail to the estate, which he valued at £716 a year, and, having ‘acquired lands and goods beyond expectation or any probability’, he changed his name to Poyntz.
Morice rebuilt North Ockendon manor house, and joined Bowyer in the Exchequer in 1613, though in a sinecurial capacity. He drew up his will ‘before my journey to the Spa’ in the summer of 1617, but derived no permanent benefit from the waters and died on 31 Jan. 1618.
