William Henn of Paradise Hill, County Clare, a future colleague on the Bench, was his cousin.
In the latter year, he was appointed a justice of the Court of King's Bench (Ireland) and held that office till his death in 1792.
[1] Elrington Ball states that Bennett was a man noted for his independence of mind: as such he was bound to clash with the formidable Lord Chief Justice of Ireland, John Scott, 1st Earl of Clonmell.
From the beginning of his tenure as Chief Justice, he regarded Bennett, who was not a man inclined to take a subservient role, as his enemy: "one adverse to me",[1] and apparently tried to block his appointment to the Bench.
[1] Bennett married Jane Lovett, daughter of Jonathan Lovett senior, of the prominent landowning family of Liscombe Park, Soulbury, Buckinghamshire and Kingswell, County Tipperary, and his wife Eleanor (Ellen) Mansergh, daughter of Daniel Mansergh of Macroom, County Cork.
