Question: How many years did the war last that Eden's great-grandfather commanded the 2nd regiment of foot? Passage:Eden's great-grandfather was William Iremonger, who commanded the 2nd Regiment of Foot during the Peninsular War and fought under Wellington (as he became) at Vimeiro. He was also descended from Governor Sir Robert Eden, 1st Baronet, of Maryland and, through the Calvert Family of Maryland, he was connected to the ancient Roman Catholic aristocracy of the Arundell and Howard families, some of whom were Roman Catholics like the Dukes of Norfolk and others Anglican such as the earls of Carlisle, Effingham and Suffolk. The Calverts had converted to the Established Church early in the 18th century to regain the proprietorship of Maryland. He was also descendant from the Schaffalitzky de Muckadell family of Denmark, and Bie family of Norway. Eden was once amused to learn that one of his ancestors had, like Churchill's ancestor the Duke of Marlborough, been the lover of Barbara Castlemaine.

Question: Is the school that house the Christ Church initially as a chapel still in existence? Passage:Christ Church was built between 1855 and 1857 to a design by the London architect Henry Martin. It was built as a chapel for Lancaster Grammar School and the local workhouse. The church was paid for and endowed by Samuel Gregson, a local industrialist and MP. In 1889 a south aisle was added, designed by the local architects Paley and Austin. It provided 152seats, and cost about 1,000. In 189495 a west baptistry was added by the same practice, then known as Paley, Austin and Paley. The same practice (by now Austin and Paley) converted the organ chamber into the Storey chapel, the organ having been moved into the south transept. In 1919 a war memorial was installed in the churchyard. It was in Derbyshire stone, high, and cost 400. This was designed by Henry Paley, then trading as Austin, Paley and Austin.

Question: Who is the current curator of the museum featured in "We're Back! A Dinosaur's Story"? Passage:One day, in the Cretaceous Period, as a Tyrannosaurus named Rex is about to devour a smaller dinosaur, he has captured by a flying saucer piloted by an alien named Vorb. He recruits him and several other dinosaurs (including Bgon the Apatosaurus, Woog the Triceratops, Jorbl the Saurolophus, Spike the Stegosaurus, Dwig the Deinonychus, and Pteri the Pteranodon) he has found for a trial of a special "vitamin" he has developed which, upon feeding it to the dinosaurs, causes them to become sentient. Vorb takes them aboard his saucer and they travel to the present, dropping them off in New York City, which at that moment is celebrating the Macy's Thanksgiving Day Parade. The dinosaurs pretend to be inflatable balloons to sneak along with the parade, but Rex mistakes one of the real dinosaur balloons to be his Allosaurus friend Worgul. The ruse is broken as a result of him accidentally popping "Worgul" and the dinosaurs flee as the crowd panics in sight of them. The police come to capture the dinosaurs soon after, but the helpful curator of the American Museum of Natural History, Dr. Miriam Bleeb, takes the dinosaurs in, and hides them from the cops by having them pretend to be life-size model dinosaurs. This satisfies the police, who leave to search for the dinosaurs elsewhere, and the curator lets them stay for the night. She reads them a bedtime story about a trilobite who wanted to walk on land, while the dinosaurs watch out the window, unsure about their future.
