What Irish expatriate was an ally of Leon Trotsky?

Question by Nan Hawthorne: What was the name of the Irish expatriate who was an ally of Leon Trotsky?
I am writing biographies of famous Irish expatriates who made their mark in the military and rebel causes of other countries. I know there was one man who worked with Leon Trotsky to bring about the Russian Revolution of 1918.

There was no Irish Bolsheviks involved with Trotsky, or who had any notable part to play in the October Revolution of 1917.
Trotsky did, however, write about the 1916 rising, and he corresponded with several Irish socialists about the prospect of a workers’ revolution and some of them attempted to get Trotsky an entry visa to allow him to live in the country – all attempts were refused.

There were a great many Irish ex-pats and people of Irish descent, who made their marks on other revolutions:
Bernardo O’Higgins is revered in Chile as the Liberator.
Ernesto Lynch Guevara is revered in Cuba.

Many of the American founding fathers had some Irish descent (although most were from the Protestant Ascendancy)
