The title Baron Verulam was created in two separate and unrelated instances: first as Baron Verulam, of Verulam, in the Peerage of England, then secondly as Baron Verulam, of Gorhambury in the County of Hertford in the Peerage of Great Britain. It was firstly created for the English philosopher and statesman Sir Francis Bacon (who was later created Viscount St Albans), and secondly created for James Grimston, 3rd Viscount Grimston (whose viscountcy was in the Peerage of Ireland).
