Hi, I am looking for a William Henry Hantzmon whose son Henry Milliard Hantzmon was born I believe in Greenbriar County in 1858. I would like to check the censuses for 1860, 70 & 80. Can anyone tell me if they are online anywhere? I have found some censuses for Russell County online. Also, was Greenbriar a part of Virginia at that time? Or West Virginia? Thanks, Mary Lou
