Sheridan was born at Castlebar, County Mayo Ireland, tge son of Henry S. Sheridan and his wife Margaret, née Martin.
He arrived in New South Wales in 1842 and was initially employed near Twofold Bay, where he had the experience of being, on his own account, "one of the first white men ever seen among the wild tribes". Subsequently, he was until 1844 employed as a property manager for Captain William Oldrey of Broulee. Sheridan retired to Brisbane but moved to Sydney in 1897, where he died at Manly on 8 June and was buried in Waverley cemetery in accordance with his Catholic faith.
He later moved north to take op position as a sub-collector of customs at Maryborough on 10 December 1859 and subsequently as a Water Police Magistrate and Immigration Agent.
He thus held several key positions in the Wide Bay and Maryborough area in the period from 1859 to his retirement in about 1890. Sheridan was respected for his integrity and deep sense of fairness and humanity, and as such, he remained throughout his life a true pioneer of compassion in regards to the rights of Aboriginal people and always keenly alert to the shady sides of the infamous Melanesian labour trade.
He thus protested in public against the Native Police system he would later raise his voice in defence of the rights of Melanesian labourers. In November 1873, he strongly criticised Maryborough hospital for refusing the treatment to a dying Aboriginal.
Sheridan subsequently joined the Customs Department in Sydney in February 1846 but his illness made him be eventually transferred to Moreton Bay (Brisbane) in February 1853, where on 31 May, he became a member of the Steam Navigation Board. Sheridan was also a trustee and a member of the board of management of the Brisbane Botanic Gardens.
