Nephew to Sampson Hanbury (1769-1835) from a family of Quaker merchants, bankers and brewers. Sampson had taken on the brewery in Brick Lane which had been there since the 17th century. Robert joined the brewery in 1819/20 and when in 1835 Sampson died childless, Robert was the heir. Reintroduced ale into the brewery products. Died in the Wapping/Shadwell area.
Don't confuse all the Robert Hanburys: This Robert's son was born as Robert Hanbury (1823 - 1867) but in 1865, on marrying the daughter of an important man he took her maiden name and so became Robert Culling Hanbury. He was a partner in the brewery and an MP. There is also Robert William Hanbury (1845 - 1903) MP. And Robert Charles Hanbury, MP for Middlesex, active in 1866. And probably others.
