Montgomery County was formed in 1821 out of Bond and Madison counties. It was named in honor of Richard Montgomery, an American Revolutionary War general killed in 1775 while attempting to capture Quebec City, Canada. Perrin's 1882 History of Montgomery County relates that the County was named in honor of Gen. Montgomery, but goes on to say that "others are dubious as to whence it received its name."
