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:
Question: What present day country was Pontus? Passage:According to the Georgian chronicles, Nana was "from a Greek territory, from Pontus, the daughter of Oligotos" whom Mirian married after his first wife died (in 292 according to Cyril Toumanoff). Nana bore Mirian two sons: Rev II, Varaz-Bakur and a daughter who married Peroz, the first Mihranid dynast of Gugark. Pontus here may refer to the Bosporan Kingdom, then a client state of the Roman Empire. Toumanoff has assumed that the name of Nana's father might have been a Georgian corruption of "Olympius" or "Olympus", a Bosporan dynast whose son Aurelius Valerius Sogus Olympianus, a Roman governor of Theodosia, is known from a Greek inscription of 306 dedicated to "the Most High God" on the occasion of the building of the Jewish "prayer house". Alternatively, Christian Settipani identifies Nana as a younger daughter of Theothorses, a Bosporan king.
