They had five sons and six daughters. Their third son, Charles William Fremantle (1834 – 1914) was the longtime Deputy Director and Comptroller of the Royal Mint. Their fourth son Sir Edmund Robert Fremantle (1836–1929) was an Admiral in the Royal Navy. Lady Cottesloe died in August 1875. Lord Cottesloe survived her by fifteen years and died in December 1890, aged 92. He was succeeded in his titles by his eldest son, Thomas.
