Pendleton County West Virginia is named after my Xth Great Uncle, Edmund Pendleton who, along with George Washington and Patrick Henry, represented Virginia in the First Continental Congress. Pendleton County was made part of West Virginia against the wishes of its inhabitants.
My great-great-grandfather lived in Frederick Co., VA, near the border with Berkeley Co., in 1860, and served in the Confederate army. After the war he moved to Kansas but his grave has a plaque on it reading "Confederate veteran."
