What is the setting of The Devil's Arithmetic by Jane Yolen in Chapters One and Two?

There are two aspects of setting that can be discussed:  setting of time and setting of place.  In Chapters One and Two of The Devil’s Arithmetic, the setting of time is the present day.  Because the book was published in the 1980s, we can safely say that is the time of the story in these first chapters.  In regards to the setting of place, this changes a bit within Chapters One and Two.  We could be very simple about it and say the setting is in the state of New York in the United States of America.  However, at the beginning, Hannah and her immediate family are in New Rochelle, New York.  Soon they are en route.  By Chapter Two, they are in the Bronx, New York.  Hannah’s family is preparing (at their own home in New Rochelle) to drive to Grandma Belle's and Grandpa Will’s apartment in the Bronx to observe the Seder meal on the first night of Passover.  They are en route during the drive when Hannah tells the story of the “walking dead” to her brother.  They are at the Bronx apartment (in later chapters) when Hannah’s experience with the Holocaust begins.
