Given the task definition and input, reply with output. In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

Passage: Dan Emmett, who claimed credit for the song, had a close association with the Snowden Family Band, a group of freed slaves who collected slave songs and began performing in the 1850s. Snowden descendants attribute Emmett's song "Dixie" to the band.
A story dating to at least 1965 says that "Old Dan Tucker" was written by slaves about a man named Daniel Tucker who lived in Elbert County, Georgia. Tucker was a farmer, ferryman, and minister who appears in records from the late 18th and early 19th centuries. The story, as related by Mrs. Guy Rucker, the great-great-granddaughter of one of Tucker's neighbors, claims that Tucker became quite well liked by the slaves in his area through his ministry to them.According to this interpretation, the lyrics address Tucker directly. The chorus, "You're too late to get your supper" is a kindhearted taunt to a man who often arrived after dark, forcing his hosts to scrape up a meal for him. The song's occasional lewdness is explained by the natural impromptu nature of its supposed origin."Old Dan Tucker" does show evidence of black influence. For example, bizarre imagery in folk versions of the song (e.g., "toothache in his heel") may be a sign of legitimate black input (or of someone poking fun of slaves who had an incomplete knowledge of English). "Old Dan Tucker" most closely resembles African music in its call-and-response refrain.Daniel Tucker was buried in Elbert County in 1818. The Elbert County Chamber of Commerce today promotes his grave as a tourist attraction due to his possible connection with the character from the song.
What is the first name of the person who wrote Dixie?
