Francis Joseph Christopher Skeffington (later Sheehy Skeffington; 23 December 1878 – 26 April 1916) was an Irish writer and radical activist, known also by the nickname "Skeffy". He was a friend and schoolmate of James Joyce (and the real-life model for a character in Joyce's novel A Portrait of the Artist as a Young Man), Oliver St. John Gogarty, Tom Kettle, and Frank O'Brien (the father of Conor Cruise O'Brien). When he married Hanna Sheehy in 1903, he adopted her surname as part of his own, resulting in the name "Sheehy Skeffington". They always spelled their joined names unhyphenated, although many sources add the hyphen. Source: Wikipedia (en)
