The Cochrane baronetcy, of Woodbrook, Old Connaught, in Bray in County Wicklow, Ireland, of Lisgar Castle in Bailieborough in County Cavan, and of Kildare Street in the City of Dublin, was created in the Baronetage of the United Kingdom on 8 October 1903 for Sir Henry Cochrane. He was governing director of Cantrell and Cochrane, mineral water manufacturers, of Dublin, and an alderman of the city.
His second but eldest-surviving son, the 2nd Baronet, was a dramatist under the name Ernest Cecil. He was succeeded by his second son, the 3rd Baronet, in 1952. The 4th Baronet succeeded his father in 1979.
While the baronetcy was created while all of Ireland was within the then United Kingdom of Great Britain and Ireland, it is illegal in what is now the Republic of Ireland for "title of nobility or of honour" to be "accepted by any citizen except with the prior approval of the Government", as clarified in Article 40 of the Irish constitution. Northern Ireland remains within the United Kingdom.
The heir apparent is the present holder's elder son Alexander Desmond Sursock Cochrane (born 1973) who is married to Irish-Canadian heiress Alannah Weston (of the Weston family) with two daughters.
