Oddly enough, I've read some sources where the word "unfortunates" was used to describe homeless members of the poverty classes in general. Here, for example, is William Booth, writing in 1890:
Wm Booth: "In Darkest England" (my italics)
Much was said concerning the disease-breeding, manhood-destroying character of many of the tenements in which the poor herd in our large cities. But there is a depth below that of the dweller in the slums. It is that of the dweller in the street, who has not even a lair in the slums which he can call his own. The houseless Out-of-Work is in one respect at least like Him of whom it was said, "Foxes have holes, and birds of the air have nests, but the Son of Man hath not where to lay His head." The existence of these unfortunates was somewhat rudely forced upon the attention of Society in 1887, when Trafalgar Square became the camping ground of the Homeless Outcasts of London.
