James McC. Montgomery acquired 1000 acres in this vicinity about 1821.Owning land on both sides of the river; he had a private ferry until granted a State franchise, Dec. 25. 1837, signed by his friend, Gov. Geo. Gilmer. It was located where the Seaboard Bridge now spans the river [Chattahoochee] & it remained the only traffic crossing on main road from Atlanta to Marietta until 1872, except the war-years, 1864-1865, in which the boats disappeared.
Refugees returning, post-war, to N. Georgia and Tennessee had no means of crossing until Thomas Moore and volunteer helpers, after 72 hours of incredible effort, constructed an emergency flat.
