I am not sure...but I think it was owned by George Meriwether....maybe if you could look at an old plat map of landowners along the river...you would find his name.....I just read a book not long ago on the civil war in Dyersburg and it was mentioned....there were several ferries ....I also think that Captain Meriwether lived on Hurt Street and that was his son
Try the University of Tennessee geography department, ask for a cartographer, ask him for any old maps of the area you are looking for. Ask for different time period maps. They have the maps recorded digitally and will charge you about $12.00 a map. Go find the county seat and look there also. Good luck.
