Biography

Numbering discrepancy: There was some family squabbling in the 1500s over the title "Earl of Thomond" which is well explained on the various Wikipedia pages referenced here:^[1]

• His great-uncle Murrough^[2] (brother of his grandfather Conor) was "1st Earl of Thomond" and "Last King of Thomond"^[3] based on tanistry, with the agreement that his nephew Donough would assume the title of 2nd Earl upon Murrough's death
• Donough (this Conor's father) was 2nd Earl
• This Conor was 3rd Earl (after much family conflict with a paternal uncle Donnell^[4] who wished to have the title)
• This Conor's son Donough was 4th Earl
