Kemeys’ family, of Norman origin, derived its name from Kemeys in the kingdom of Gwent.
The likelihood that Kemeys would inherit the Monmouthshire lands probably explains his election to Parliament for a county seat in 1628, but the earls of Worcester may also have facilitated his return, as he was later mentioned as a ranger for the 4th earl in Wentwood Forest.
Kemeys’s estates increased significantly upon the death of his nephew, Edward Kemeys of Cefn Mabli, in 1636, while the death of Edward’s only daughter shortly after made Nicholas’s title more secure. Contemporaries estimated the value of the combined estates at £1,400-1,500 p.a.
Kemeys was knighted in May 1641, an indication that the king hoped to win his support, as was his receipt of a baronetcy a year later. He was probably the candidate who stood against Henry Herbert† of Coldbrook for one of the Monmouthshire seats at a by-election in March 1642, which followed the death of his brother-in-law, (Sir) Charles Williams*.
The outbreak of the Second Civil War allowed Kemeys to venture back into Wales, when he became the royalist Governor of Chepstow. He continued to hold the castle after the town had fallen to Oliver Cromwell*, but was killed when Isaac Ewer’s forces stormed the garrison on 25 May. The subsequent sequestration of his estate was handled by his son, Sir Charles, who compounded for £3,500 in 1652, and shortly thereafter procured an adminisration for his father’s lands.
