I have been researching my ancestors in Pendleton County W.V. (Va, before the later unpleasantness with the North.)
Seems My Great Great Grandfather and his father and Brothers made and sold Black Powder near the Mouth of the Seneca River is said county, for years before my Great Gr4andfather was born. It was Jacob Harper and his sons. Jacob's son Jesse is my Great Great Grandfather.
Fun facts that you learn when researching.
No wonder I got into BP in the late 60's!
