[2][3] Seán South was born in Limerick, where he was educated at Sexton Street Christian Brothers School, later working as a clerk in a local wood-importing company called McMahon's.

[citation needed] He was a member of a number of organisations, including Clann na Poblachta (who he worked for during the 1948 election), Sinn Féin, the Gaelic League and the Legion of Mary.

[4] In Limerick he founded the local branch of Maria Duce,[1][4] a rabidly conservative and anti-Semitic Roman Catholic organisation led by Father Denis Fahey, where South also edited both An Gath and An Giolla.

South accused these films of promoting a "stream of insidious propaganda which proceeds from Judeo-Masonic controlled sources, and which warps and corrupts the minds of our youth.

"[13][14] South also claimed that the American film industry was controlled by "Jewish and Masonic executives dictating to Communist rank and file.

"[13] In his letters, South also denounced Irish trade unions, and praised the activities of Senator Joseph McCarthy in the United States.

South's funeral was held on 5 January 1957 and drew massive crowds numbering in the thousands, including members of the clergy and the Mayor of Limerick City Ted Russell.
