Richard Blayney, 4th Lord Blayney
Born 1629/30 at Castleblayney (Ireland)
Baron from Dec 1669 
died 5th Nov 1670 in Dublin, Ireland
Through advances made [£6,000], the wealthy Englishman Thomas Vincent had become the owner of the Blayney estate but in 1653 Richard made a "prudent marriage" with Thomas Vincent's eldest daughter and she brought the estates back to the Blayney family as a dowry , . "He secured also by special provision in his marriage settlement a home for himself and his wife, with four servants and two horses, in his father-in-law's house [Thomas Vincent], and doubtless induced the latter to come to Ireland under the protection of the Cromwells, in whose favour he stood high." 
Suspected of royalist plotting in 1649 but became favoured by Oliver Cromwell who in 1656 made him "Custos Rotulorum" (Keeper of the Rolls of the Peace) within the county of Monaghan and 'Escheator' of Tyrone (1656) and the whole province of Ulster (1659) by Richard Cromwell.
[Escheat=the reverting of property to the Crown, when there is a failure of persons legally qualified to inherit or to claim, so 'Escheator' is one who arranges this].
"His lordship Richard Blayney, Esq., 'Escheator' of Tyrone, and others were empowered to inquire 'What estate, right, and title Oliver Cromwell, or any of his predecessors, kings or queens of England, at any time had to any castles, manors, lordships rectories, tythes, &c., within the county of Tyrone, by virtue of any Acts of Parliament or Council, or by reason of any attainder, escheat, or otherwise, who were then possessed thereof, and by what title, which commission was then executed by an inquisition, taken August 9, 1688, at the town of Strabane.' 
1659 "For the County of Monoghan, The High Sherif Richard Blaney" .
M.P. in the Irish Parliament for County Monoghan 1661-1666 [44c], to the first parliament after the restoration  and MP in the UK Parliament for Cavan, Formanagh and Monaghan in 1956 .
