Slide 3 – Thomas Viscount Fauconberg. Thomas, his grandson, succeeded as Viscount Fauconberg, who nmarried first, Mildred, daughter of Viscount Castleton, and second, in 1657, Mary, third daughter of Oliver Cromwwell. There were great national rejoicings at this marriage. However, Thomas, Viscounct Fauconberg, no doubt did a wise thing in marrying Mary Cromwell, as thereby he saved much of the family estates from further spoilation. He survived untill 1700, having seen much of public life, and adding great lustre to his name and family.
