In New York Mulcahy set about creating a directory of Irish political exiles, hoping to unite all the various Irish organisations in the city under one united banner. On 6 February 1877 Mulcahy discovered the former head of the American
Fenian Brotherhood,
John O'Mahony, dying in a New York garret and despite his best efforts, he was unable to save his life. Mulcahy subsequently accomplished O'Mahony's body back to Ireland, where he was laid to rest in
Glasnevin Cemetery. Mulcahy later lamented in a written piece for
the Nation reporting upon the well-attended funeral that "we seem to set more value on the dead patriot's bones than on his living brains". There was much fallout from Mulcahy's returning of O'Mahoney to Ireland; Mulcahy had been told by
Jeremiah O'Donovan Rossa that the Fenian Brotherhood would pay him $1,000 to cover the cost of the expense of the trip, however, he only received $537. Mulcahy later sued the Fenian Brotherhood for the remainder, but they protested that they could not be held responsible for Rossa's promises. The court ruled against Mulcahy in January 1894. The case soured the opinion of the leader of
Clan na Gael John Devoy on Mulcahy, but
John O'Leary continued to hold him in high regards. Mulcahy opposed the
"New Departure", a movement that sought to unite physical force Republicans with constitutionalists such as the
Irish Parliamentary Party. Mulcahy was suspicious of
Charles Stewart Parnell, who he feared had dictatorial ambitions. Mulcahy spent the last years of life prospering; he ran a successful medical practice in
Newark, New Jersey and it was there he died on 13 September 1900. ==References==
