When she had finished her prayers for those beneath the roof of Tara, her father, mother, sisters, three dead babies and "all the poor souls in Purgatory," she clasped her white beads between long fingers and began the Rosary.
When Ashley came to the part of the prayers concerning the souls in Purgatory, which Carreen had marked for him to read, he abruptly closed the book.
So, in deference to public opinion, he skipped all mention of Purgatory.
Ashley knew that half the people present had never heard of Purgatory and those who had would take it as a personal affront, if he insinuated, even in prayer, that so fine a man as Mr. O’Hara had not gone straight to Heaven.
There are no more uses of "purgatory" in the book.
