Cogan, Patrick (1902–77), politician, was born 2 January 1902, only son and fourth among five children of Hugh Cogan, farmer, of Mullnamast, Moone, Co. Kildare, and Katherine Cogan (née Nolan) of Paulville, Tullow, Co. Carlow. The family lived at Ballykilduff, Tullow, Co. Carlow. Educated at Ballyconnell national school, Co. Wicklow, he joined the Gárda Siochána in the mid 1920s and served as secretary to Supt. John Feore in Kilkenny, retiring in 1928 to take over the Ballykilduff farm. A prominent member of the Irish Farmer's Federation and its political wing, the National Agricultural Party, he was unsuccessful as a Farmers' candidate for Wicklow in the 1937 general election but was elected a member of Carlow county council (1937–60). Elected as an independent TD (Wicklow) in the 1938 general election, he was to the fore of the movement to establish parish councils during the Emergency. Appointed deputy leader of Clann na Talmhain on its merger with the National Agricultural Party (1943), he resigned from the party (1947) owing to his disagreement with its vociferous radical element. In the 1948 general election he was elected as an independent farmer candidate, initially supporting the inter-party government before withdrawing his support (1950) in opposition to the political favouritism shown in the filling of the sub-postmastership in Baltinglass. In 1951 he supported the minority Fianna Fáil government; joined the party (October 1953); and stood unsuccessfully as a Fianna Fáil candidate for Wicklow in the 1954 general election. Between July 1954 and 1957 he served as a Fianna Fáil senator. He died at St Bridget's Hospital, Carlow, 5 January 1977.
He married (March 1927) Annie (d. 1986), daughter of Richard Grainger, farmer, of Westcourt, Callan, Co. Kilkenny. They had three children and lived at Ballykilduff, Co. Carlow.
