After the planned royal marriage came to nothing, the Dowager Duchess finally settled on the 21-year-old
Lord John Russell, younger brother and
heir presumptive of the
Duke of Bedford. The death of her brother-in-law in Spain on 23 October, 1732 made Lady Diana Duchess of Bedford and
châtelaine of
Woburn Abbey. The trauma induced the
premature birth of a son named John, possibly in
Cheam. His baptism was registered on 6 November, but he died within a day and was buried in
Chenies on 11 November.
Lord Hervey reported that it was deemed so important to prevent the Duchess from learning about her son's death "that after grand consultation ... it was determined a Child should be brought to replace the Defunct, till she was strong enough to hear the truth and be told it was only a pretender". The Duke soon became obsessed with fathering an heir, and was deeply upset when, few months after the birth of their child, the Duchess's next pregnancy ended in
miscarriage. The Duchess found herself reproached for not looking after herself properly during the pregnancy. Although they no longer lived together, grandmother and granddaughter still saw each other frequently and exchanged two to three letters weekly when they were separated. The Duchess of Bedford remained the closest confidante of the Dowager Duchess of Marlborough and was kept informed about all family affairs, including financial matters. == Death ==
