George Richard Russell is the Viscount Marble and he is Lynn and Sarah's father. Gentle and kind, he loves his children dearly and will do anything for their sakes. He is away on business trips a lot in order to pay back the money he owed to the bank for his businesses, with the Marble Mansion as the collateral. George works hard to the point of endangering his health. He is pressured by his father, the Duke Woburn, to marry the Baroness Wavebury to pay off his debts.
