Petersen, Christine. The Miller. (Colonial People.) New York: Marshall Cavendish, 2012.
There is a wealth of information contained in this book about the milling profession during the colonial period. Much of the information is too advanced for the elementary school student, yet the larger print will probably put off middle school readers. This would be useful to gain an understanding of this occupation if one's ancestor was engaged in it.
This is part of the Friday series on children's literature and genealogy.
