I'm looking for information on my great-grandfather, Zebulon/J.B. Portwood. I have been told he worked for the railroad and was killed in a sawmill accident. I assume he was in the construction part of it. I know he was alive in 1900, Paulding county, Burnt Hickory district, and died sometime between 1907 and 1910. Any info would be appreciated. I have hit a brick wall.
