led a career as an attorney. He became a well-known lecturer for the Irish National League of America, and he traveled across the US continuing to criticise Parnell and the wider Home Rule movement as being too centered on Westminster, and instead advocated educating the Irish populace in non-violent republicanism. Despite his close contacts with Clan na Gael, Brennan opposed the Fenian dynamite campaign of the 1880s on the grounds that it harmed the reputation of the Irish republican movement. Brennan's former colleague, Patrick Egan, had also emigrated to Nebraska and was running a successful real-estate and insurance brokerage in the nearby city of Lincoln. When Egan was appointed as United States Ambassador to Chile in 1889, Brennan took over his business and managed the company for the remainder of his life. He died in Omaha, Nebraska on 19 December 1912, and is buried in an unmarked grave at Holy Sepulchre Roman Catholic Cemetery, 4912 Leavenworth Street, Omaha, Nebraska.<ref>Omaha World-Herald, The Public Pulse. 9 July 1919 page 6.</ref> Politics and activism Brennan's address to the crowd at the Tenant Rights meeting at Irishtown, County Mayo on April 20, 1879, that led to the formation of the Land League: . . .
