The Blayney's had been "reduced to a state of destitution as a result of the rebellion."  requiring Edward to mortgage both the family's estates in Monaghan and Castleblayney to Thomas Vincent, a wealthy London merchant, in 1649 and 1653 . Edward was unmarried and died with no male heir, so his only surviving brother Richard inherited the title .
Thomas Vincent became connected with Ireland as mortgagee of the estate of Edward, third Lord Blayney, whose father had died fighting against Owen O'Neill. Ultimately, through the advances which he made, Vincent became owner of the estate; but Lord Blayney's brother Richard, who succeeded him as fourth Lord Blayney, by "a prudent marriage" with Vincent's eldest daughter, recovered the CastleBlayney estates (but not Monaghan) .
Edward was buried on 9th December 1669 at St. Martin-in-the-Fields Church, Covent Garden, London. [44c]
The Baronage then passed to his younger brother Richard, the 4th Lord Blayney
