Thank you for the heads-up, the marriage has been added.
To barber: Through marriage, women are allowed to use the title of their husbands. If the title is passed on to the next in line because the bearer of the title dies, the widow is called a "dowager", especially if the next in line is married, and there is another woman to use the title. That way people can distinguish between the two women. So you could say that a dowager is the widow of someone who once had that title.
