Lady Caroline's favorite sister, Emily Lennox, married and went to live in Ireland in 1747. In 1750 and 1751, the Lennox sisters' parents died in quick succession, leaving three younger daughters, Louisa, Sarah, and Cecilia, aged eight, six, and one. In his will, the 2nd Duke of Richmond, remembering Lady Caroline's reckless elopement, passed over her and instructed that his three youngest daughters be entrusted to the care of their sister Emily and her husband, James FitzGerald, 20th Earl of Kildare. Lady Caroline resented this slight but hoped to redeem herself by presenting her younger sisters at court and helping them make good matches. The Kildares' allegations that the Foxes were responsible for Lady Sarah Lennox's embarrassing rejection by the young King George III, as well as her disastrous marriage to Sir Charles Bunbury soon afterwards, provoked a quarrel between the sisters that was not healed until shortly before Lady Caroline's death.
