English Roman Catholic priest and martyr
About Thomas Thwing
Lived 1635 – 1680 (aged 44–45).
Thomas Thwing (1635–1680) was an English Roman Catholic priest and martyr, executed for his supposed part in the Barnbow Plot, an offshoot of the fabricated Popish Plot invented by Titus Oates. His feast day is 23 October.
Early life His father was George Thwing, Esq. of Kilton Castle, Brotton, and Heworth Hall. His mother was Anne, daughter of Sir John Gascoigne and his wife Anne Ingleby, and sister of Sir Thomas Gascoigne, 2nd Baronet, of Barnbow Hall, Barwick in Elmet. Both parents were Yorkshire recusants. The martyr Edward Thwing was his great-uncle.
Thomas was born at Heworth Hall, Heworth, York, and educated at St Omer and at the English College (Douai), ordained a priest and sent to minister at the English Mission in 1665, which he did for roughly 14 years. Until April 1668, he was chaplain at Carlton Hall, the seat of his cousins, the Stapleton family. He opened a school at Quosque, the Stapletons' dower-house. He lived on Hepworth Lane, in Carlton, Selby.
In 1677 Mary Ward's Institute of the Blessed Virgin Mary (I.B.V.M.) began its foundation at Heworth Manor (also called Heworth Hall), which had been purchased in 1678 by Thomas' maternal uncle, Sir Thomas Gascoigne, from Sir George "for my niece Ellen," Thomas' sister, after which it was given to the order. Thwing's sisters, Anne, Catherine, Ellen (Helen) and cousin Jane, were instrumental to the founding of the order, Dolebank Convent and the Bar Convent. It was at the Manor House that Thwing would become chaplain and where he was arrested in early 1679.
"Barnbow plot" At the time of the Titus Oates scare, or "Popish Plot", two servants, Bolron and Mowbray, who had been discharged from Sir Thomas Gascoigne's service for dishonesty, sought vengeance and reward by revealing a supposed plot by Gascoigne and others to murder King Charles II. At first, the informers made no mention of Thwing. Nevertheless, Gascoigne, his daughter Lady Tempest, Thwing, and others were arrested on the night of 7 July 1679, and removed to London for trial at Newgate.
John Philipps Kenyon observed that Thwing was executed for conspiracy, despite the logical difficulty of a conspiracy without any other conspirators.
Posthumous Thomas Thwing was declared Venerable by Pope Leo XIII on 9 December 1886 and beatified by Pope Pius XI on 15 December 1929 and henceforth known as the "Blessed Thomas Thwing".
