Francis William Browne, 4th Baron Kilmaine JP DL (24 March 1843 – 9 November 1907) was an Anglo-Irish politician and landowner.
Browne was born in London, the eldest son of John Cavendish Browne, 3rd Baron Kilmaine, and his second wife, Mary Law, daughter of politician Charles Ewan Law (by his father's first wife, he had three half-brothers who died unmarried before their father.)
[4] They had one son, John Edward Deane Browne, who married Lady Aline Kennedy, daughter of the 3rd Marquess of Ailsa.
[5] Lord Kilmaine killed himself in Paris in November 1907 by jumping from the fourth-floor of the Hotel d'Iéna.
He had reportedly suffered from "acute nervous disease" and chronic sleeplessness, and had gone to Paris for treatment.
