Baron Segrave (Seagrave) is a title in the Peerage of England. It was created by writ in 1283 for Nicholas de Segrave, and the title is drawn from a village in Leicestershire now spelled Seagrave.
The 6th Baron Segrave had previously succeeded to the title of Baron Mowbray, and thereafter, the two baronies have remained united, apart from a period of about a hundred years. For several generations they were subsidiary titles of the Dukes of Norfolk, and in 1777, they both went into abeyance with the death of the 9th Duke of Norfolk.
The second creation, by writ was for Nicholas de Segrave of Barton Segrave in the County of Northampton in 1295, becoming extinct on the death of his daughter Maud in 1335.[2]
In 1831, a new Barony of Segrave was granted to Colonel William Berkeley, later created first Earl FitzHardinge, but this creation became extinct when he died without an heir in 1857.
Despite this interlude, the original barony of Segrave was still in existence, and in 1878, it was called out of abeyance for Alfred Stourton, 23rd Baron Mowbray, some two weeks after he had similarly recovered the barony of Mowbray. The titles have remained united since.
