Scope and Contents

The collection centers around three people: Albert G. A. Harnickell, Raphael Sanchez Boone, Jr., and Ada [Boone] O'Brien. The papers of Sanchez Boone and Ada O'Brien are inter-related by references to the same people, places, and to each other. They were siblings and many of Sanchez Boone's letters were written to or by Ada O'Brien, as well as other family members. The Harnickell papers have no connection to the papers of Sanchez and Ada. Albert Harnickell, however, was the brother of Wilhelmine Harnickell who was the grandmother of Sanchez and Ada. Names mentioned often in the collection are George O'Donnell Boone and Wilhelmina [Boone] Hechter. These were other siblings of Sanchez and Ada. Raphael Sanchez Boone, Sr. and Ada [O'Donnell] Boone are the parents of the four children.

The Harnickell section begins with two hand-written manuscripts about the Civil War and the Fourteenth Regiment of the New York State Militia. The later papers deal with Albert Harnickell's patent for a Spelter Furnace, his brokerage business and his partnership in the Old Dominion Copper Co.

Much of the Sanchez Boone section is personal correspondence with family members (especially parents) and friends during World War II. There is also a large amount of official Army correspondence such as daily bulletins and special orders. Sanchez took several correspondence Army Extension Courses in organization of various areas of the military and map reading. The manuals, papers and examinations from these are present in the collection. After his return from the war, Sanchez was a great fire buff and was active in the community. There are a few papers which cover this period and give a picture of the extent of Sanchez's community involvement.

The papers of Ada Boone O'Brien are more recent and are split between personal correspondence written during her trip to Europe and travel brochures. The travel brochures give illustrations of various parts of Europe, particularly France and Ireland.

At the end of the collection is a checking account ledger from the National Mechanics Bank of Baltimore. It was owned by Frank Brown, who is of uncertain relationship to the Boone-O'Brien-Harnickell family. The ledger provides a detailed account of his financial transactions from 1895 to 1905.
