Simeon baronets of Grazeley (1815)

The Simeon baronetcy, of Grazeley in the County of Berkshire, was created in the Baronetage of the United Kingdom on 22 May 1815 for John Simeon, Member of Parliament for Reading and Senior Master of the Court of Chancery. The evangelical cleric Charles Simeon was his brother.

The 2nd Baronet represented the Isle of Wight in the House of Commons. He married Louisa Edith, daughter and heiress of Sir Fitzwilliam Barrington, 10th and last Baronet, of Barrington Hall (see Barrington baronets). The third Baronet was also Member of Parliament for the Isle of Wight while the fourth Baronet sat for Southampton. The eighth Baronet was Professor of Political Science and Law at the University of Toronto.

As of 2024 the present Baronet has not successfully proven his succession and is therefore not on the Official Roll of the Baronetage, with the baronetcy considered dormant.
