She firstly married Augustus Henry FitzRoy, 3rd Duke of Grafton on 29 January 1756, at her father's house in St James's Square, by special licence of the Archbishop of Canterbury. The marriage was witnessed by Lord Ravensworth and Francis Seymour-Conway, 1st Earl of Hertford. Together they had three children:
