marriage to Joseph Chamberlain bore a son, Neville, who became prime minister. Emily was also the cousin of William Kenrick MP. Joseph Chamberlain was then the Leader of the Liberal Unionists, and with his assistance Sir Thomas was instrumental in getting the Welsh Water Bill through Parliament and getting Birmingham made an assizes town. Like his father, Sir Thomas was also Mayor of Birmingham, holding office from 1884 to 1887, the year Queen Victoria was received by him when opening Birmingham's Victoria Law Courts. He was subsequently invited later in 1887 to Windsor Castle where he was knighted by the Queen. He died on 28 July 1893 and is buried alongside his family at Key Hill Cemetery. Colonel Ernest Martineau (1861–1952), son of Sir Thomas, was Lord Mayor of Birmingham between 1912 and 1914; his first cousin, Neville Chamberlain, replacing him in this role in 1915. Robert Francis (16 May 1831 – 15 December 1909), brother of Sir Thomas, was an alderman, secretary of the Birmingham and Midland Institute, chairman of the Technical School committee, trustee to Mason Science College, and then a member of the council of its successor institution, the University of Birmingham. He and his family were the third generation of Martineaus to live at Highfield Road, Kings Norton, Edgbaston. National and international interests The intermarried Martineau and Lupton clan counted many aldermen and lord mayors, in both Birmingham and Leeds respectively, amongst their kin. Their Unitarian faith and Liberal (Unionist) political beliefs resulted in their combined commitment to many national concerns. For example, Sir Raymond Unwin's concept of the garden suburb greatly interested Robert Francis Martineau and his cousin, Francis Martineau Lupton. International issues were also of great concern to the family; Robert Francis Martineau welcomed the abolitionist William Lloyd Garrison to his home when the American visited Birmingham on 7 July 1877 and two days later, Martineau's relative, Joseph Lupton, had Garrison as a guest at his Leeds house from 9–15 July. Lord Mayors of Birmingham Members included five generations, father to son, of Mayors or Lord Mayors of Birmingham: Robert Martineau (1798–1870), Mayor of Birmingham, 1846–47 Sir Thomas Martineau (1828–1893), Mayor of Birmingham, 1884–87 Ernest Martineau (1861–1952), Lord Mayor of Birmingham, 1912–14 Sir Wilfrid Martineau (1889–1964), Lord Mayor of Birmingham, 1940–41 Denis Martineau (1920–1999), Lord Mayor of Birmingham, 1986–87 A blue plaque, erected in 2008 by the Birmingham Civic Society in the Council House,
