The sixth 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.
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.
