- Born: 1811c Died: 1862
Surveyor and engineer, active from the 1820s to the 1860s. Denis Leahy, second son of PATRICK LEAHY and elder brother of EDMUND LEAHY and MATTHEW LEAHY , was probably born circa 1811 in Co. Tipperary. He was trained by his father, whom he joined in practice in Clonmel circa 1828. In 1830 he went to England with his father and brother Edmund to survey the proposed Liverpool to Leeds railway line for ALEXANDER NIMMO . By 1833 he was living at Cabra, near Thurles, but, after his father and Edmund had been appointed county surveyors for the East and West Ridings of Cork respectively in 1834, he joined them in Cork, in order to assist them in their public and private work. Following Edmund's resignation and his father's dismissal in 1846, he returned to Thurles. In the early 1850s he moved to London. In December 1861 his brother Matthew, Superintendent of Public Works in Trinidad, died on the island after only four months in the post. Denis applied successfully to succeed him. He arrived in Trinidad in September 1861 but survived little longer than Matthew, dying on the island on 21 December 1862. He left a widow, Elizabeth, whom he had married in London in May 1853, and two sons, Albert, later a successful doctor, and William Henry.
