John Jeffreys (c.1623-1689) was a Welsh soldier, landowner and politician, much of whose career was spent in Ireland.
He fought in the English Civil War on the Royalist side, and later sat in the Houses of Commons of both England and Ireland.
The salary of £300 a year was no doubt welcome to Jeffreys, even though, despite Jenkins' reference to his poverty, he was probably clear of debt by this time.
James II, who succeeded to the throne the following year, continued him in office, despite his rumoured opposition to repeal the Test Act, on account of his "long service and sufferings".
James also took seriously Jeffreys' petition of 1686 pleading for more resources: it seeks that within two years of the hospital's foundation most of the original sources of funding had dried up.
She married firstly the English-born judge Arthur Turner, justice of the Court of Common Pleas (Ireland), who died prematurely in 1684.
Having disregarded her father's instructions over his burial and her own marriage, she defied him a third time by selling his beloved home, the Priory, which he had inherited from his cousin Sir Herbert Price, to an unrelated family called Jeffreys from Llywel.
