[4] The couple had five sons and five daughters: The Clanwilliams were extravagant spenders, the Viscount dissipating large sums on horseracing, gambling, and keeping mistresses.
Lord Clanwilliam was forced to sell and mortgage his Cork and Kilkenny estates to pay off the debts; they were also charged with providing marriage portions for his daughters Anne and Catherine in 1788 and 1789.
Clanwilliam found himself obliged to begin liquidating the Tipperary estate in 1793, a process that continued until 1805, at the cost of providing portions for his remaining younger children.
[7] Gilford's consent was needed to break the entail, but as he had contracted debts of his own and married the Bohemian, Roman Catholic, noblewoman Countess Caroline Thun without the approval of his parents in October 1793, he was in no position to obstruct them.
[9] By September 1800, Clanwilliam suffered badly from dropsy and left his wife at Gill Hall, on the Gilford estate, for his mistress and his Dublin townhouse.
