## Marriages and children

Dillon married twice. His first wife was Elizabeth Barnewall, only daughter of Thomas Barnewall of Irishtown, who was the second son of Thomas Barnewall, 7th Baron Trimleston.

Bartholomew and Elizabeth had a son:

* Thomas (living in 1541), married Anne, daughter of Sir Thomas Luttrell, and was father of Sir Robert Dillon

—and two daughters:

* Anne, married Nicholas Kent of Davidstown
* Ismay, married three times. First to John Fleming of Stephenstown, a grandson of James Fleming, 7th Baron Slane, and was the mother of Thomas Fleming, 10th Baron Slane. Secondly to Richard Tath of Cookstown, and thirdly to Sir Thomas Barnewall, second son of John Barnewall, 3rd Baron Trimlestown and his eldest child by his second wife Margaret FitzLeones.

## Career

Dillon was an official at the Court of Exchequer (Ireland) by 1505 and became a Baron of the Exchequer in 1507. He was promoted Chief Baron in 1514 but removed after a year, for reasons unknown. He was Deputy Treasurer of Ireland from 1516 to 1522, when he became a judge of the Court of King's Bench (Ireland). On 15 January 1533 he was made Lord Chief Justice of the King's Bench for Ireland but died suddenly soon after.

According to Elrington Ball, at a time when the Irish ruling class were deeply split between supporters (the so-called Geraldines) and opponents of the 9th Earl of Kildare, Dillon was one of the most committed Geraldines, and spent much of his time in England defending the Earl of Kildare's interests.
