[Q]: 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.

[Q]: Question: Were either of the men that Slater accompanied aboard the  HMS Shearwater born in Scotland? Passage:In 1874 he accompanied the botanist Isaac Bayley Balfour and George Gulliver aboard HMS Shearwater on an expedition to observe the transit of Venus on Rodrigues. In addition to studies of the flora and fauna, Slater excavated the subfossil bones of extinct birds, including the Rodrigues solitaire (Pezophaps solitaria) and Rodrigues starling (Necropsar rodericanus). His records were used by the zoologists Albert Günther and Alfred Newton to write the first scientific description of the Rodrigues starling in 1879. During a stay in Mauritius in 1875 he and George Gulliver explored the flora, the herpetofauna, and the aquatic avifauna. In 1885 he traveled with Thomas Carter to Iceland. Based partly on his work there, he wrote the Manual of the Birds of Iceland, published in 1901. In 1897 Slater described the short-tailed parrotbill (Paradoxornis davidianus) and the sulphur-breasted warbler (Phylloscopus ricketti). Together with William Bernhardt Tegetmeier and Frederick William Frohawk, he wrote the fifth volume of British Birds With Their Nests and Eggs (1898). In 1877 Slater was elected a Fellow of the Zoological Society of London (FZS). He was also a member of the British Ornithologists' Union.
