We had a thread on this over a year ago (I think I started it, actually) and it mysteriously disappeared. Perhaps a moderator thought we were getting into dangerous territory?
Anyway, Chris, the Baxter family was Catholic; Sir Cosmo Duff Gordon was raised a Catholic owing to an Italian mother but the entire family converted to Anglicanism when he was a teenager (someone else posted this on the other thread, and Randy Bryan Bigham, I believe, posted that
Lady Duff Gordon was raised a Catholic owing to an Irish grandmother and he is the expert on her ladyship). The other aristocrat - the Countess of Rothes - was not Catholic but her father converted and willed the family seat of Prinknash Park to a monastary.
Dr. Minahan and Daisy were Catholics but I don't know about Lillian Minahan (the surnames in her family tree tend to be rather WASPY). Thomas McCaffrey was buried in Notre Dames des Neiges Cemetery so he was probably Catholic. On the other thread, someone wrote that Miss Young was buried in a Catholic cemetery while not being a Catholic herself. It was also posted that Thomas Cardeza converted to Catholicism upon his marriage, causing a temporary rift with his mother. We can assume that the Spanish Penascos and the South American passengers (the Carraus, Mr Artagratayvia (sp?)) were Catholic, and French passengers (Omont, Aubart, DeVilliers, Rheims, Chevre, Marie DeMeugot Spencer) were Catholic. Though, of course, the world does have French Protestants.
Jacques Futrelle was apparently of Huguenot descent, though contemporary newspaper accounts mentioned that his daugther Virginia went to a school called Notre Dame.
As far as the Irish passengers, Purser McElroy was a Catholic (prominent, though not a passenger). Mr. Flynn, in spite of his Irish name, was NOT a Catholic but Brady was, and I think Brereton and McGough were. I don't remember about Timothy McCarthy. Peter Daly had an Irish name and a French mother and he married a Peruvian, so I assume he was Catholic. The Spedden's nurse and family confidante, Margaret "Muddy Boons" Burns, was a Catholic. According to Dr. Leader's obit, a "Father O'Farrell" officiated at her funeral, but I doubt she was a Catholic.
Annie May Stengel's funeral was a solemn high requiem mass at the Church of Good Counsel in Newark. I'm not sure if that sort of service means Catholic or not, and I don't know what religion her husband was.
Hope this helps.
