In answer to: "How far back do directories go for the city of Martinsburg? Susan Curelop researching GRIMM/KOGELSCHATZ/MATTHEAI/SNYDER in MD then Martinsburg" The Martinsburg Library has R.L. Polk's Martinsburg City Directory from 1913-date, which lists name, address, telephone and occupation of city residents. They also have Cumberland Valley Railroad Directory, 1877-78, containing a general directory of the citizens of Martinsburg, WV and Thompson Brothers' directory of Martinsburg, 1898-99; lists name, address, and occupation of town residents. The Berkeley County Historical Society has a very limited collection of the R.L. Polk directories. I think the earliest is in the 1930s. Mollie Seibert Ziegler
