Patriot Priest tells one man's personal experience over several epochs and areas of history. It is also, in part the story of one unique individual, author Patricia Daly-Lipe's great uncle, Msgr. William A Hemmick. Born in Pittsburgh, PA, and raised in Europe, he became fluent in five languages. When the First World War broke out, he felt committed to help the troops. After the war, he was proclaimed the Patriot Priest of Picardy by the Army and Navy. After years spent in Paris, William Hemmick was asked by the Vatican to come to Rome. Ultimately he became the only American Canon of St. Peter's representing the Knights of Malta to the Holy See.

It was he who performed the nuptials of American film star Tyrone Power and Linda Christian. He also converted the future Queen Astrid of Belgium.
