|Summary:||Isaiah Sanborn Lang, a farmer, was born in 1823 and lived in Candia Village, New Hampshire. Lang married Martha Ladd in 1848, and they had several children. The papers of Isaiah S. and Martha Lang span the period 1858 to 1928 and consist of correspondence to Lang and his wife from various relatives and a small amount of business records. Approximately one-half of the correspondence is from Lang's maternal uncle, David M. Sanborn. All the Sanborn correspondence was written from Maryland locations, including Baltimore City, Marriottsville (Howard County), and Hanover (Howard County). In his letters, Sanborn calls himself an abolitionist, although he mentions his slave, Elize, several times. He also discusses economic and social conditions in Baltimore during the Civil War. Additional correspondents of the Isaiah and Martha Lang include relatives who moved to the frontier area of Minnesota: Ann Jane Campbell, A. E. Clay, Elizabeth Clay, James P. Clay and Ursula Stone. These letters contain economic and domestic information about frontier farming in Minnesota. A teacher friend, W. A. Worthen, of Laurel, Maryland also wrote several letters to Isaiah Lang describing his new life in the "South" and providing information about Lang's uncle, David M. Sanborn.
