For instance, one excerpt references a grandfather who is deeply affected by having to leave his house, indicative of a narrative involving loss and displacement. Another excerpt describes a wedding and mentions a character named Grandison who returns home in a very weary state, suggesting a story involving a long journey with a likely reference to slavery.
