Cadwallader (Davis) Blayney, 10th Lord Blayney
Born 1769 in Ireland
Baron from 13 Nov 1775 
Died 2 Apr 1784
Cadwallader (Davis) Blayney, became the 10th Lord Blayney in 1775 on the death of his father Cadwallader. However he died without an heir  on 2 April 1784, unmarried (he was 15 at the time of his death ). Interred at CastleBlayney. His brother [Andrew] inherited the title  and became the 11th Lord Blayney.
However, one US account claims the tenth Lord Blayney had at least three sons, James,
John and Cadwallader, who emmigrated to the USA between 1795 & 1832. I have demonstrated that this is not correct - see
