Not many months later her own father was a prisoner in Dumbarton Castle, and during the fifteen months in which he lay there, Grisell was still the messenger, not only to him, but to his friends in various parts. Her early childhood may have been unharassed, but Grisell Home's girlhood was a careful and anxious one. On the discovery of the Rye House Plot, Baillie of Jerviswoode and Home of Polwarth, innocent men both, were denounced as traitors to their King. Baillie was taken, and after several months of imprisonment in London, so heavily loaded with chains that his health completely broke down, he was brought by sea to Edinburgh in stormy November weather which kept the ship a fortnight on its way. A dying man when he was put in the Tolbooth, he yet had to undergo many exhausting examinations and a farcical trial, with "Bluidy Mackenzie" for chief inquisitor, and on Christmas Eve, 1684, he gallantly and cheerfully met a martyr's death at the Market Cross of Edinburgh. Sir Patrick Home's denunciation was longer in coming than that of his friend, and not until November 1684 was the warrant for his apprehension issued. He, good man, had no desire for martyrdom; moreover, at that time he already possessed ten children, whose future as orphans was likely to be wretched, and so Sir Patrick sought concealment from the hounds of the law. Foiled in laying hold of him, the law seized his eldest son, Patrick, and cast him into prison. Two days after Jerviswoode's death, the lad petitioned the Privy Council for release. He was but "a poor afflicted young boy," he said, loyal to his principles and with a hatred of plots, and only craved liberty that he might "see to some livelihood for himself" and "be in some condition" to help and serve his disconsolate mother and the rest of his father's ten starving children. Most grudgingly was the boon bestowed, and not until the boy had obtained security for his good behaviour to the extent of two thousand pounds sterling was he allowed to return to the Merse.
