Question: How old was Alois Hitler Jr.'s wife, when her father threatened to have him arrested for kidnapping? Passage 1:After the 2010 Texas Longhorns football team finished with the first losing season since 1997, Texas began the 2011 NCAA Division I FBS football season unranked in the preseason Associated Press poll for the first time since 1998, although they ranked 24th in the preseason Coaches' Poll. Texas defeated its first four opponents, including two that they had previously lost to in 2010. Texas would go on a two-game losing skid against top 10 teams Oklahoma and Oklahoma State before winning against Kansas and Texas Tech. The game against Kansas was the first shutout for a Texas football team since beating Baylor 63-0 in 2005. Texas would once again enter a two-game losing skid before beating Texas A&M in the Lone Star Showdown. The Longhorns would lose to Baylor before becoming selected to play in the 2011 Holiday Bowl. Texas would go on to win 21-10 against California, finishing the season with an 8-5 record.
 Passage 2:In 1909, Alois Hitler Jr. met an Irishwoman by the name of Bridget Dowling at the Dublin Horse Show. They eloped to London and married on 3 June 1910. William Dowling, Bridget's father, threatened to have Alois arrested for kidnapping, but Bridget dissuaded him. The couple settled in Liverpool, where their son William Patrick Hitler was born in 1911. The family lived in a flat at 102 Upper Stanhope Street. The house was destroyed in the last German air-raid on Liverpool on 10 January 1942. Nothing remains of the house or those that surrounded it, and the area was eventually cleared and grassed over. Bridget Dowling's memoirs claim Hitler lived with them in Liverpool from 1912 to 1913 while he was on the run to avoid being conscripted in his native Austria-Hungary, but most historians dismiss this story as a fiction invented to make the book more appealing to publishers. Alois attempted to make money by running a small restaurant in Dale Street, a boarding house on Parliament Street and a hotel on Mount Pleasant, all of which failed. Alois Jr. left his family in May 1914 and he returned alone to the German Empire to establish himself in the safety-razor business.
