Mathias Klein
A Checklist of American Coverlet Weavers by John W. Heisey (The Colonial Williamsburg Foundation, 1978) notes the following about Mathias Klein: “According to recorded coverlets, he was weaving in Montgomery County, Ohio, from 1839 to at least 1842. W.W. Reilly & Co. lists him as a coverlet weaver in Montgomery County, spelling his name ‘Clein.’”
Weaving a Legacy: The Don and Jean Stuck Coverlet Collection by Clarita S. Anderson (Columbus Museum of Art, 1995) illustrates three Mathis Klein coverlets from the Stuck Collection. The book notes Klein was born circa 1810 in Germany, and that he was active from 1840 to 1852 in Jefferson, Montgomery County, Ohio.
Further p4A.com research indicates that his known coverlets run until 1859, and that he often included the words “the State of Ohio Montgomery County” in them.
