谁和弗里德里希·恩格斯约会过？

Mary Burns (29 September 1821 – 7 January 1863) was a working-class Irish woman, best known as the lifelong partner of Friedrich Engels. Burns was born and lived most of her life in Manchester, England.

Not much is written about Burns. The only direct references to her that have survived are a letter from Karl Marx to Engels on learning of her death, saying she was "very good natured" and "witty", and a letter from Marx's daughter, Eleanor, saying she was "very pretty, witty and an altogether charming girl, but in later years drank to excess". No images of Burns are known to exist.
