This material was added to the William Cyrus Howard family collection in 2003 by one of the co-executors of his son's estate, Lester Hey, and Hey's daughter Marilyn H. Duncan. It includes correspondence between Howard family members, records of William Cyrus Howard's brother Alfred's estate, account books, and some business records. The account book at the end of this series belonged to William Cyrus Howard's father, of the same name.
