On the seventh of May, 1765, Curwen's only child Ann was born; and was christened by the Reverend John Graves of King's Church, of which both husband and wife had become communicants shortly after their marriage in order to compromise between their respective Congregational and Baptist affiliations. The record of this birth, as well as that of the marriage two years before, was stricken from most copies of the church and town annals where it ought to appear; and Charles Ward located both with the greatest difficulty after his discovery of the widow's change of name had apprised him of his own relationship, and engendered the feverish interest which culminated in his madness. The birth entry, indeed, was found very curiously through correspondence with the heirs of the loyalist Dr. Graves, who had taken with him a duplicate set of records when he left his pastorate at the outbreak of the Revolution. Ward had tried this source because he knew that his great-great-grandmother, Ann Tillinghast Potter, had been an Episcopalian.
