Bartholomew was born at Riverston, County Meath, eldest son of Sir James Dillon and his wife Elizabeth Bathe.[1][2] His father was a Baron of the Exchequer.[3] His father's family was Old English and descended from Sir Henry Dillon who came to Ireland with Prince John in 1185.[4] His mother was a daughter of Bartholomew Bathe of Dollardstown Castle, Athy, County Kildare.
He leads the list of his brothers below as the eldest:
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.[14]
Dillon's younger brother Robert founded the branch of the family that would later hold the title Earl of Roscommon. By birth and marriage the Dillon brothers belonged to the small Anglo-Irish ruling class of the Pale.
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.[21]
