Levi Orendorf Harn, born in 1809 in Maryland, was a Confederate soldier and a printer/stage proprietor. He married Zerua Ann Duval of Maryland. They had four children: Allen Duval Harn, William Tyler Duval Harn, Carroll Prather Duval Harn, and Samuel Marcelius Harn.

Dr. Allen Duval Harn was born on July 31, 1836, in Hagerstown, Frederick County, Maryland. He was a practicing physician in Houston, Texas. Dr. Harn married Josephine Camp, daughter of Ira Malcolm Camp and Eliza Collins. They had eight children: Camp Collins Harn, Allen F. D. Harn, Jr., Traetta Estelle Harn, Ann Zern Harn, Bessie Blonde Harn, Dorsey Fred Harn, and Lydia Lillie Roberta Harn. Bessie Blonde Harn, daughter of Allen and Josephine Harn, married George Edward Caldwell.

William Tyler Duval Harn, born in May 1838, was the son of Levi O. and Zerua A. D. Harn and the brother of Dr. Allen Duval Harn. In 1861, William Harn married Mary Agnes Duer, born in October of 1841. She was the only child of Johann Christian Friedrich Duer and Mary Stanley.

Scope and Content Note

The Duer-Harn-Caldwell Papers which date from 1838 to 1873 are comprised of two groups: the Charles Duer Papers and the Harn-Caldwell Papers. The Charles Duer Papers are comprised of a letter and three legal documents. The letter is dated in 1873 and is from W. R. Baker to C. F. Duer indicating that he would pick up Mrs. Duer at Hammond, but is unable to notify her by telegraph because the railroad is not supposed to pick up passengers at the point where she wishes to board the train. Legal documents include an 1838 Degree of Master Mason to Christian Duerr by Friedrich Martens and an 1842 Degree of Master Mason to Christian F. Duer by Luder E. Bohles. There is also a signed certification from the Harmony Lodge No. 2, Independent Order of Odd Fellows, City of Houston, Texas, that indicates C. F. Duer as a member of good standing.

The Harn-Caldwell Papers are comprised of correspondence, financial and legal documents, a photograph and a creative work. Correspondence includes an 1854 letter from L. O. Harn to his son Allen D. Harn advising him to stay in college. There is also an 1864 letter from William Walton to Dr. A. D. Harn, at the Cheneyville, Louisiana, hospital regarding housing arrangements and expressing gratitude for his faithfulness to the sick. The financial document is an 1872 bill for merchandise from James H. French, San Antonio, Texas, to George W. Caldwell. Legal documents include a circa 1854 testimonial awarded to Allen D. Harn by the Trustees and Teachers of the Hagerstown Academy “as evidence of the general propriety of his deportment and diligent attention to study.” There is also an 1856 Masonic degree as Grand Master of Olive Branch Lodge No. 114 to George W. Caldwell.

Included in the group is an 1854 photograph of Allen D. Harn, M.D., graduate of St. James College. The creative work is a poem entitled “Long, Long Ago, Long Ago” transcribed for Miss Mary A. E. Duval by a friend.
