John De Mowbray was born in 1328. He was the son of John De Mowbray and Joan Plantagenet.
He married about 1349 to Elizabeth De Segrave, who was sole heir of her father, John de Segrave, by his wife Margaret Plantagenet. John De Mowbray held lands in right of his wife, in Leicestershire; the manors of Segrave, Silby and Montsorrell. He held Melton and Mobray in his own right.
In Warwickshire he held the castle and manor of Caludon.
He was involved in the wars with France. He was summoned to parliament as “John de Mowbray of Axholme” 9 Oct 1368. He was killed in a fight with the Turks at Thrace near Constanople, after he took the cross and left on Crusade to the Holy Land.

I found an entry in an old book that says that Elizabeth Segrave inherited the manor of Romford from her parents:
The Environs of London: Counties of Herts, Essex & Kent - Page 184
by Daniel Lysons - 1796
“The manor of Romford is first mentioned in a record of the year 1299, when it was held of Adam de Cretinge, by Henry de Winchester, a Jew convert. Sir Walter de Manny, who died in 1372, was seised of the manor of Romford in right of Margaret his wife, daughter and coheir of Thomas Brotherton, Earl of Norfolk, and widow of John Lord Segrave. The inheritance went to Elizabeth, daughter of Margaret's first husband, and wife of John de Mowbray; whose son, Thomas Duke of Norfolk, died seised of it, 1400.”
