Who were the three main characters described in chapter 1

Juana and Kino were the main characters described in Chapter One.

Kino

A prototypical Mexican-Indian who works as a pearl diver, he begins the story as a devoted father and husband to Coyotito and Juana, respectively. Kino is the central character of the story, an Œeveryman' who finds himself becoming increasingly violent, paranoid and defiant as he faces opposition from others after he finds the pearl, and resorts to assaulting Juana and murdering those who threaten him.

Juana

The mother of Coyotito and the wife of Kino, Juana is, as her name suggests, the representation of woman for Steinbeck in the story. She dutifully supports her husband, despite his worsening treatment of her, but warns him against the dangers that the pearl can bring to the family. Juana remains steadfast throughout the story and devoted to maintaining her family. She even refuses to obey Kino when he suggests that they take separate paths to avoid the trackers.

Coyotito

The infant son of Kino and Juana, after he is stung by a scorpion, the doctor refuses to treat him because his parents have no money. Although Juana seemingly cures him with a seaweed poultice, he receives treatment from the doctor only after Kino finds the pearl. When Kino and Juana are hunted by trackers after escaping La Paz, one of the trackers shoots Coyotito in the head as they hide in a cave.
