What is dowager viscountess?

A dowager viscountess is the widow of a viscount, who continues to hold the title and rank of viscountess even after her husband's death. She may also be referred to as the widowed viscountess or the dowager lady. The term "dowager" distinguishes her from the current viscountess, who is the wife of the current viscount. In the traditional British peerage system, the title of viscount is below that of an earl and above that of a baron. The role of a dowager viscountess may involve ceremonial duties, social obligations, and possibly managing the estate associated with the title.
