Dowageress

Dowageress: noun. A woman who has married a dowager, thereby gaining her titles and responsibilities through marriage, and thus entirely legally. A dowageress has yet to exist and is currently only hypothetical in nature, mainly due to the restrictions on same-sex marriage in many countries. This is however due to change quite soon and thus a dowageress is no longer a ludicrous idea, as it may have been viewed in the past.
