Question: Who is Prince Henry, Duke Of Cumberland And Strathearn's paternal grandmother?
Sentence (from "Lavinia Ryves"): The trial was most considered remarkable, perhaps, for the claims made by Dr. Walter Smith, Lavinia's barrister, that George III had been privately married to a Quaker, Hannah Lightfoot, and that in consequence thereof, neither George IV nor Queen Victoria had any right to the throne.
Relevant evidence: No
