Baron Grandison
Extinct barony in the Peerage of England
From Wikipedia, the free encyclopedia
Baron Grandison was by modern doctrine a title in the Peerage of England created for two brothers, Sir Otton de Grandson and Sir William Grandison, who were summoned to Parliament in 1299. Any hereditary barony for Sir Otho lapsed on his death in 1328, as did that for Sir William on the death of his grandson Thomas Grandison in 1375.[1]


The family originated in what is now the Swiss canton of Vaud by the name of Grandson, the anglicised Grandison was a shortening of the Latin form Grandisono. The family origins lay in the grant of land by Lake Neuchâtel during the last years of the Second Kingdom of Burgundy.

Abeyance

In 1858,[4][5][6] after five centuries in abeyance, Sir Henry Paston-Bedingfeld, 6th Baronet of Oxburgh Hall (eldest son of Sir Richard Bedingfeld, 5th Baronet) was declared by the Committee of Privileges to be one of the co-heirs of the Barony of Grandison "through "the families of Paston, Tuddenham, Patteshull, and Grandison, heir to Dame Katherine Tuddenham, in whom one-fourth of a third of the representation of the Barony of Grandison had vested."[7]
