Thomas Plunket, 2nd Baron Plunket

Thomas Span Plunket, 2nd Baron Plunket (1792–1866), was Bishop of Tuam, Killaly and Achonry.

Plunket was the first son of William Plunket, 1st Baron Plunket and his wife, Catherine (née McCausland). He was educated at St John's College, Cambridge. He served as Dean of Down from 1831 to 1839 before being elevated to the episcopacy as Bishop of Tuam, Killala and Achonry in 1839, a position he held until his death in 1866. He moved to live on a private estate at Tourmakeady, where he evicted many Catholic families for not sending their children to the Protestant school. In 1852 Plunket increased his holdings to over 10,000 acres, and his 203 tenants were recorded as paying an annual rent of 2000 pounds. Plunket was a champion of the “second reformation”, an evangelical campaign which ran from the 1820’s to the 1860’s.

On the death of his father in 1854, he became the 2nd Baron Plunket. On his death, he was succeeded as Baron Plunket by his younger brother. His middle name is taken from his maternal grandmother, Elizabeth (née Span). He was buried in the churchyard of his now-ruined church at Tourmakeady.
