Harriot Coutts after 1822 was left with Thomas's large fortune and bank partnership, but also with the hostility of Coutts's family from his first marriage. She was mercilessly lampooned. A pamphlet Mr. Percy Wyndham's Strictures on an Impostor was written in alignment with Wewitzer's financial interests, and taxed her with falsehood and ingratitude. Ernest Hartley Coleridge, biographer of Coutts, commented that it proclaimed "the wrongs and sufferings of the decayed actor, Ralph Wewitzer", and declared it "probable that Wewitzer, who was old and poor, had been interviewed and had complained of ingratitude and neglect, but it is evident that he had not unfolded the tale in which he figures as hero or villain."
