Charles William Mills, 2nd Baron Hillingdon (26 January 1855 – 6 April 1919) was a British banker and Conservative politician who sat in the House of Commons from 1885 to 1892, speaking once, in 1889.
He was a lieutenant in the Queen's Own West Kent Yeomanry and a partner in the banking firm of Glyn, Mills & Co.[2] In the 1885 general election, Mills was elected as member of parliament (MP) for the inceptive safe seat of Sevenoaks in which he owned The Wildernesse, setting up community allotments and an orphanage there.
In the same year Hillingdon commissioned Edwin Lutyens, who was then working locally, to design Overstrand Hall.
Nikolaus Pevsner considered it one of Lutyens' most remarkable buildings, but other critics of the day thought it "lacked the picturesqueness of his best works".
He died in April 1919, aged 64, and was succeeded in the barony by his second son Arthur, the MP for Uxbridge, elected unopposed to replace his elder brother.
