Baron de Freyne

Baron de Freyne, of Coolavin in the County of Sligo, is a title in the Peerage of the United Kingdom. It was created in 1851 for Arthur French, 1st Baron de Freyne, with remainder to his younger brothers John, Charles and Fitzstephen. He had earlier represented County Roscommon in the House of Commons and later served as Lord Lieutenant of County Roscommon. French had already been created Baron de Freyne, of Artagh in the County of Roscommon, in 1839, also in the Peerage of the United Kingdom but with normal remainder to heirs male. Lord de Freyne was childless and on his death in 1856 the barony of 1839 became extinct. He was succeeded in the barony of 1851 according to the special remainder by his younger brother John, the second Baron.

On his death the title passed to another brother, Richard, the third Baron. In 1851 he married Catherine Maree, daughter of Luke Maree, by a Catholic priest. Afterwards a question arose as to the validity of the marriage with she being a Roman Catholic and he a Protestant and they were again married in 1854 in the Church of Ireland. By then they had had three sons, Charles French (1851–1925) (Member of Parliament for County Roscommon), John French (1853–1916) and William French (1854–1868). However, due to the uncertainty over the first marriage Lord de Freyne was succeeded by his eldest son born after the marriage of 1854, Arthur French, the fourth Baron. His eldest son, the fifth Baron, was killed in action at the Battle of Aubers Ridge in 1915. He was succeeded by his half-brother, the sixth Baron. As of 2010 the title is held by the latter's grandson, the eighth Baron, who succeeded his father in 2009.
