Russell had two siblings: brother Frank (nearly seven years older than Bertrand), and sister Rachel (four years older). In June 1874 Russell's mother died of diphtheria, followed shortly by Rachel's death. In January 1876, his father died of bronchitis following a long period of depression. Frank and Bertrand were placed in the care of their staunchly Victorian paternal grandparents, who lived at Pembroke Lodge in Richmond Park. His grandfather, former Prime Minister Earl Russell, died in 1878, and was remembered by Russell as a kindly old man in a wheelchair. His grandmother, the Countess Russell (née Lady Frances Elliot), was the dominant family figure for the rest of Russell's childhood and youth.
