"Lady Peel" is a term that refers to the wife of a baronet of the United Kingdom, or the equivalent in other countries. This term was derived from the surname of Sir Robert Peel, the two-time Prime Minister of the UK and the founder of the Metropolitan Police Service. Though the term "Lady Peel" is used specifically for the spouse of a baronet, there are other informal synonyms that can be used to refer to a woman of high social status, such as a noblewoman or aristocrat. These include duchess, countess, marquess, baroness, viscountess, princess, and queen.
