Ellen (Elizabeth) Dickson (1819 – 4 July 1878), also known as Dolores, was an English ballad composer. She was born in Woolwich, England southeast of London. Ellen was the third daughter of General Sir Alexander Dickson. She had been physically disabled since a young age, and her chosen Latin pseudonym, Dolores, which means sorrows and bodily pains, reflects that aspect of her personal life. Ellen inherited her father’s talents for mathematics and his analytical intellect. She lived most of her life and died in Lyndhurst, England.
