I was puzzled by your post until I realized my mistake, it was my great-great-great grandfather (born 1789 died 1863) who fought in the War of 1812. His grandson (my great-grandfather) was in a Confederate division in the Civil War.
We are not as far removed generation wise as some would have us believe. A local fellow passed away last year here whose father served in Confederate regiment and his Sergeant was my great great grandfather. The Regiment was commanded by William Faulkner’s father.
