Who all headed west on the Joad truck?

Pa, Ma, Granma, Granpa, Al, Connie, Rose of Sharon, Uncle John, Ruthie, Winfield, Tom, Noah, Casy, and Noah.

Pa said, "Ma, you an' Granma set in with Al for a while. We'll change aroun' so it's easier, but you start out that way." They got into the cab, and then the rest swarmed up on top of the load, Connie and Rose of Sharon, Pa and Uncle John, Ruthie and Winfield, Tom and the preacher. Noah stood on the ground, looking up at the great load of them sitting on top of the truck.
