Apparently in a letter to the Pall Mall Gazette dated March 1884 it is stated that Robert, who became the 1st Viscount Hampden, appears to have had two marriages. The first one was solemnized at Fleet Prison but all official records of this have been de- stroyed. Records obtained from Westminster School identify that four of his sons were pupils there and the titles later went to his two sons from his marriage to Constantia de Huybert. It seems that the first two sons were given very large funds in trust, and one of them was Frances’ father Dr John Trevor.
