Personal life
On 29 August 1831, he married firstly Harriet Georgiana Cosby, youngest daughter of Thomas Cosby, of Stradbally Hall and his wife Charlotte Elizabeth Kelly (daughter of Rt. Hon. Thomas Kelly, Second Justice of the Common Pleas of Ireland). Together, they were the parents of two daughters and three sons, including:
Hon. Charlotte Elizabeth Trench (1832–1854), who died unmarried.
Hon. Frederick Sydney Charles Trench (1839–1879), who married Lady Anne Le Poer Trench, eldest daughter of William Trench, 3rd Earl of Clancarty and Lady Sarah Juliana Butler (eldest daughter of Somerset Butler, 3rd Earl of Carrick), in 1867.
Hon. Cosby Godolphin Trench (1844–1925), who married Maria Musgrave, eldest daughter of Sir Richard Musgrave, 4th Baronet of Tourin and Frances Mary Yates (a daughter of John Ashton Yates MP for County Carlow), in 1873.
Hon. Harriette Mary Trench (d. 1884), who married, as his first wife, Maj. Hon. Frederick Le Poer Trench (1835-1913), second son of the 3rd Earl of Clancarty, in 1883. Frederick was the older brother of her brother's wife Lady Anne.
After his first wife's death on 25 February 1845, he married Elizabeth Oliver Gascoigne in Aberford on 10 February 1852. She was the second daughter of Richard Oliver Gascoigne, of Parlington Hall and Mary Turner (daughter of Sir Charles Turner, 1st Baronet, of Kirkleatham). He lived much of the year at Castle Oliver, which was built in 1845 by his second wife and her sister Isabella.
Trench died, aged 75, at Clonodfoy (otherwise known as Castle Oliver) and was buried at the family's mausoleum at Woodlawn, County Galway, a week later. His older son Frederick having predeceased him in 1879, he was succeeded in the barony by his grandson Frederick. His second surviving son Cosby, who inherited Castle Oliver, was a soldier and magistrate.
