What kind of life did Lucy live? What effect does Lucy’s death have on the poet?

In William Wordsworth's "She Dwelt Among the Untrodden Ways," the girl Lucy appears to have lived a life of relative anonymity, isolation, and loneliness. For instance, in the first line Wordsworth says that "She dwelt among the untrodden ways," suggesting that she lived alone far from conventional communities. Furthermore, at the end of the first stanza he claims that Lucy was "A Maid whom there were none to praise / And very few to love" (3-4), which suggests that few people loved or even cared about her. Despite this fact, Wordsworth concludes his poem by saying "she is in her grave, and, oh, / The difference to me!" (11-12). 

All in all, Wordsworth suggests that, though Lucy lived in relative obscurity, he found her life to be incredibly meaningful. Thus, the poem becomes an exploration of the ways in which even the simplest of people can still live lives of great significance. Since Wordsworth communicates this compelling idea in a few short lines, it's hardly surprising that this poem has proven to be one of his most popular compositions.
