Q: Question: How old was von der Goltz' great-grandfather during WWI? Passage 1:After Prague, the production moved to the Bahamas. Several locations around New Providence were used for filming during February and March, particularly on Paradise Island. Footage set in Mbale, Uganda, was filmed at Black Park, a Country Park in Buckinghamshire, on 4 July 2006. Additional scenes took place at Albany House, an estate owned by golfers Ernie Els and Tiger Woods. The crew returned to the Czech Republic in April, and continued there, filming in Prague, Planá and Loket, before completing in the town of Karlovy Vary in May. A famous Czech spa, Karlovy Vary, in German known as the Karlsbad, was used as the exterior of the Casino Royale, with the Grandhotel Pupp serving as "Hotel Splendide". The main Italian location was Venice, where the majority of the film's ending is set. Other scenes in the latter half of the film were shot in late May and early June at the Villa del Balbianello on the shores of Lake Como. Further exterior shooting for the movie took place at properties such as the Villa la Gaeta, near the lakeside town of Menaggio.
 Passage 2:Gamble was born in the townland of Duross, Lisnarick, County Fermanagh, Ireland. He studied civil engineering, worked in the Queen's Surveying Office, and participated in the Northern Ireland survey. He emigrated to the United States in 1838. Since he had experience as a dragoon in the British army, he enlisted as a private in the 1st U.S. Dragoons and rose through the ranks to become Sergeant Major by 1839. While in the Army he married Sophia Steingrandt, daughter of King's German Legion Feldwebel Georg Steingrandt, on 6 May 1841, and they had 13 (by some accounts 15) children together. After fighting in the Seminole Wars, he was discharged in 1843 and worked as a civil engineer for the Board of Public Works in Chicago and lived in Evanston, Illinois. His house is now used by the Anthropology Department of Northwestern University.

After further education in Hannover, New York, and Freiburg, he joined the radio orchestra of Hamburg's Norddeutscher Rundfunk at the age of 21. Two years later he left in order to focus on his career as a soloist, chamber musician, and conductor. He is now musical leader of the Freiburger Barockorchester. From 1997 to 2004 he held a professorship with the Hochschule für Musik Würzburg. In October 2004 he was called to a professorship in violin and baroque violin at the Hochschule für Musik Freiburg.
