Grace Carson-Copenhaver was my great great grandmother. Will exchange any information you need on the Copenhaver Mills, Kanawha County WV. line who relocated to California and Coal Center, Pennsylvania in the mid Monongahela valley.
Can add to Lloyd Gale Sparks book.
There is also a book by John E. Hildreth, The Copenhavers of Northern West Virginia,1989. This book documents the early Koppenhoffer/Copenhaver line. It is not probable that this is the "Wolfgang Koppenhoffer" line.
