Dennis Cosley was born June 20, 1816 near Martinsburg, Virginia. In 1831, he went to Fort Louden, Franklin County, Pennsylvania, where he learned spinning, dyeing and weaving. He remained in Pennsylvania for fifteen years. In 1837, he operated a mill in Bridgeport, Pennsylvania, which subsequently burned. To get the necessary funds to purchase his own mill, he conducted a school for four years and in 1844, bought one at Fayetteville, Pennsylvania. Cosley also bought a loom for weaving coverlets, which he fortunately kept in his home, for in 1845 this mill burned as well. In 1846, Dennis and his brother George, moved to Xenia, Ohio, where they built a log loom house at the rear of Dennis Cosley’s residence, and where he produced a great number of coverlets without a center seam. Cosley did his own dyeing and, at the outbreak of the Civil War, dyed blankets for the Union Soldiers. He left Xenia, Ohio in 1864 and never wove another coverlet thereafter. Instead he ran a woolen mill in Miami County, Ohio, for three years and later had a store in Troy. He retired in 1890 and died in 1904.

Peter Uhl was born in Germany circa 1806, and after settling in Ohio, wove coverlets (some of which are undated) in Portage and Trumball Counties from 1838 to 1841. His corner blocks contained either his name and location or his name, location, client’s name and the date.

Peter Lorenz (Lorentz) was born in France circa 1801. After moving to America, he worked in Wayne County, Indiana, and Greene and Montgomery Counties in Ohio. His known coverlets range from 1836 to 1847, most of which are dated, and his corner blocks have either his name and date or simply his name.

Nathaniel Young was a New Jersey weaver whose work was a mystery for years because of its similarity to the work of David D. Haring, with whom he may have worked – or from whom he might have purchased patterns. This similarity caused his work to be attributed to Bergen or Hudson County, but it is now believed that he worked in Pine Brook, Morris County instead, based on that location having been woven into a corner block of one of his coverlets.

His known dated coverlets range from 1833 to 1842. Some coverlets are undated, and he appears to have used several different corner blocks: a pear, a tulip with a bud, a rose with four leaves, and a stylized foxglove. The location of his name, date and client information varies depending on which corner block was used, but he did mis-spell the word “Wever” (weaver) when present in his work.

N. Beaver worked at Keagy’s Globe Factory in Bedford County, Pennsylvania. Of his known coverlets, none are dated, but the corner blocks contain the factory name and location, his name and the words “Made By”.

John Kaufman was born in 1812 in Lower Saucon Township, Lehigh County, Pennsylvania. He worked in Hilltown Township in Bucks County, and his known coverlets date from 1837 to 1849.

John Klein (circa 1834 to 1901) immigrated to America from Germany and settled in Indiana with his family. He, his father, and three brothers wove in Shelby County until John moved to Hamilton County in 1857 with his brother Andrew.

John Kittinger, who was located in Springfield, Portage County, Ohio, has known coverlets dating from 1836 to 1840. His corner blocks contained his name, date and location, and sometimes his client’s name.

John Hamelton was a Pennsylvania weaver who worked in Machenoy and Jackson Townships in Northumberland County. He worked in Jackson Township circa 1837 to 1843. His Machenoy coverlets include the initials “L.T.Y.”, and those from Jackson have the initials “P.A.N.” on them. The meaning of both of these sets of initials is a mystery at this time.
