Question: How many homes did the architect of the Yablanski House design? Passage 1:MCA embarked on a big marketing campaign to tout Willis after she recorded her first album on the label, the 1990 album Well Travelled Love. MCA ensured that Willis was interviewed by several national magazines including unusual venues like Vogue and Mademoiselle. Her voice appeared in the 1991 Ridley Scott-produced movie Thelma and Louise, singing "Little Honey." Willis also had a small part in Tim Robbins’ 1992 film Bob Roberts. Willis appears as the young woman standing in a shallow stream in Dwight Yoakam's video of "A Thousand Miles from Nowhere," as well as a member of Vince Gill's "pickup band" in his Don't Let Our Love Start Slippin' Away video. She was also nominated for Top New Female Vocalist of the year at the 1993 ACM Awards along with Faith Hill and Lari White (Hill wound up winning the award). Despite of all the publicity and positive reviews from most reviewers, Well Travelled Love and Willis’s subsequent albums for MCA (Bang Bang in 1991 and Kelly Willis in 1993) sold modestly and received very little radio play. During this time, Willis felt uncomfortable with the way she was marketed by MCA. In 1994, MCA released Willis from her contract.
 Passage 2:The Yablanski House was built in 1906-1907 to the designs of Austro-Hungarian architect Friedrich Grünanger (1856–1929) on the order of the wealthy financier and former mayor of Sofia Dimitar Yablanski (1859–1924). The exterior decoration was the work of the royal decorator of the Bulgarian Royal Family, Andreas Greis. Architecturally, the house was designed in the Baroque style with some Renaissance elements, with the interior stucco done in the Rococo style. The mansard floor is an important feature of the house's artistic design, together with the balcony railings of wrought iron and the several female sculptures. The furniture and the materials were specially supplied from Vienna. The house's architecture draws heavily from an earlier work of Grünanger's, the Royal Palace in Sofia. Notably, the architect's home in Salzburg, where he later moved and subsequently died, is almost identical to the Yablanski House.
 Passage 3:Lady Eden was born in 1920, the daughter of Major Jack Spencer-Churchill (1880–1947), the younger brother of Winston Churchill, by his marriage to Lady Gwendoline ("Goonie") Bertie (1885–1941), a daughter of the 7th Earl of Abingdon, who had been married in 1908. She is thus a niece of Winston Churchill, who was Prime Minister during the Second World War, and a granddaughter of Lord Randolph Churchill, Chancellor of the Exchequer 1886–87, and his wife the American society beauty Jennie Jerome. Her paternal great-grandfather was the 7th Duke of Marlborough, and her maternal great-great-grandfather the 3rd Marquess of Londonderry, half-brother of the 2nd Marquess, who, as Viscount Castlereagh was Foreign Secretary during the Congress of Vienna of 1815 that followed the Napoleonic Wars.
