Zeebo: Calpurnia's son, leader of songs at First Purchase African ME Church. Literate, lined the music.
Lula: Woman who confronted the children at Calpurnia's church. She made them feel unwelcome and unwanted.
Rev. Sykes: Pastor of the black church, closed the doors until the group could raise 10 dollars more for Helen Robinson.
Aunt Alexandra was waiting at home for the kids. She was there to help Atticus with the kids throughout the summer during the trial, and she also stated she was there to be an influence on Scout, a feminine influence.
The answer to this question (the identities of these people) can be found in Chapter 12. This is the chapter in which Calpurnia takes Scout and Jem to the First Purchase Church. This is the black church in Maycomb.
Lula is the woman who confronts the three of them. She does not like the fact that Calpurnia has brought the white kids. She thinks the church should be for blacks only.
Zeebo is the garbage collector. He welcomes the kids and tells them not to take Lula seriously.
Rev. Sykes is the pastor of the church.
As was mentioned in the previous post, all three of these characters can be found in Chapter 12 when Calpurnia takes Jem and Scout to Sunday service at First Purchase African M.E. Church. Lula is an ornery woman who challenges Cal's decision to invite Jem and Scout to their African American church. Lula does not think that white children should be allowed at First Purchase African M.E. Church and displays her prejudiced feelings as soon as she sees Cal with the Finch children. Zeebo is Calpurnia's son. He is one the few literate African Americans in the community and leads the congregation in singing hymns. Zeebo is also Maycomb's garbage collector and treats the Finch children with respect. Reverend Sykes is the pastor at First Purchase African M.E. Church. He takes up multiple collections and has the doors locked until the members give ten dollars for Helen Robinson's cause.
