Question: At what age was the Countess von Gelichen's brother when he inherited his cousin's Marquesstate of Hertford in 1870? Passage 1:The Qing dynasty was founded not by Han Chinese, who form the majority of the Chinese population, but by a sedentary farming people known as the Jurchen, a Tungusic people who lived around the region now comprising the Chinese provinces of Jilin and Heilongjiang. Although the Ming dynasty held control over Manchuria since the late 1380s, Ming political existence in the region waned considerably after the death of the Yongle Emperor. What was to become the Manchu state was founded by Nurhaci, the chieftain of a minor Jurchen tribe in Jianzhou in the early 17th century. Originally a vassal of the Ming emperors, Nurhaci started to take actual control of most of Manchuria over the next several decades. In 1616, he declared himself the "Bright Khan" of the Later Jin state. Two years later he announced the "Seven Grievances" and openly renounced the sovereignty of Ming overlordship to complete the unification of those Jurchen tribes still allied with the Ming emperor. After a series of successful battles against both the Ming and various tribes in Outer Manchuria, he and his son Hong Taiji eventually controlled the whole of Manchuria. Soon after the establishment of the Qing dynasty, the territory of today's Primorsky Kray was made part of the Government-general of Jilin, and along with the lower Amur area was controlled from Ninguta (a garrison town south of today's Mudanjiang).
 Passage 2:Elma Muros-Posadas (born January 14, 1967 in Magdiwang, Romblon) also known as the "Long Jump Queen" of the Philippines and a heptathlon champion, is a former member of the Philippine Track and Field National Team and now a legend in Philippine track and field history who specialized in long jump. She also competed in the heptathlon, 100m and 400m hurdles, 100m, 200m, and 400m sprint alongside the "Sprint Queen" of the Philippines and also fellow legend, Lydia de Vega. Elma is one of the foremost track and field athletes produced by the Philippines under the Marcos Regime's National Sports Program, Gintong Alay, that was launched in 1979, but was eventually disbanded in 1986 due to the People Power Revolution and the ousting of Ferdinand Marcos. Later on Gintong Alay was disbanded and became the Philippine Sports Commission (PSC) which was established in 1990.
 Passage 3:When the Countess von Gleichen's brother, Francis, inherited his cousin's Marquessate of Hertford in 1870, the Queen granted her the rank and style of the daughter of a marquess by Royal Warrant of Precedence, entitling her to prefix Lady to her name. However, she continued to use her comital title until 15 December 1885, when it was gazetted in the Court Circular that the Queen had granted her permission to share, within the British Empire, her husband's princely title. Henceforth she was known as HSH Princess Victor of Hohenlohe-Langenburg, although this changed neither her legal rank nor her title in the German Empire. In accordance with the original Coburg grant, her children were also Count/Countess von Gleichen and, although granted unique precedence before the daughters and younger sons of English dukes in 1913, they never received authorisation to share their parents' princely style at the Court of St. James's, and were known by their comital title (dropping, however, the von) until George V Anglicised their style in 1917, along with the styles of members of his own family who bore German titles. Princess Victor did not live to undergo that demotion in titulature.
