Brigadier-General James Dayrolles Crosbie, CMG, DSO, JP, DL (19 August 1865 – 18 December 1947) was an Irish Justice of the Peace, High Sheriff and Deputy Lieutenant of County Kerry, and a senior officer in the British Army during the First World War.
He was a Justice of the Peace and became High Sheriff of Kerry in 1894 and the same year married Maria Caroline Leith on 28 July.
Active on local committees, he became the chairman of the 3 km-long Tralee & Fenit Railway Company, which opened in 1887.
With the outbreak of the First World War, he rejoined the army in 1914 as commander of the 11th Battalion Lancashire Fusiliers, was promoted to brigadier-general in the 12th Infantry Brigade and returned home in 1917.
The castle buildings were used by the Royal Irish Constabulary from 1890, and were subject to arson attacks in 1912 (after Crosbie attended a Unionist meeting in Tralee and seconded a motion against the Home Rule bill being debated in the UK Parliament) and again after their sale in 1921, in a fire started by Irish Volunteers.
After his return from Russia, he resided in County Wicklow before buying Muircambus House in Fife, settling there with his family.
