Sotheby’s auction notes include this biographical sketch, "Lady Hillingdon, Alice Marion Mills (née Harbord 1857-1940) was the fourth daughter of the 5th Baron Suffield. Her husband was the wealthy banker and businessman Charles William Mills, the 2nd Lord Hillingdon whose father owned an exceptional collection of eighteenth century portraits. It is most likely that the portrait hung at Overstrand Hall in Norfolk, the large home given to the Hillingdon's as a wedding present by the bride's father and altered by Edwin Lutyens. The Hillingdons had married in 1898 but it was not a happy union and Lady Hillingdon’s diary in 1912 contains the following famous aphorism which betrays her feelings towards her husband; 'I am happy now that Charles calls on my bedchamber less frequently than of old. As it is, I now endure but two calls a week and when I hear his steps outside my door I lie down on my bed, close my eyes, open my legs, and think of England.’”
According to her article in thepeerage, she bore two children.
