The town of Ransomville was established in 1842 by the Ransom and Curtiss families and was named after William Henry Harrison Ransom. The Curtiss family, led by brothers Gideon and Capt. Gilbert Curtiss, were the first to settle in the area in the 1820s, establishing the early links with neighboring towns.

The son of immigrants from Sullivan County in the Hudson River Valley, W.H.H. Ransom arrived in Niagara County in 1839 and built a farm that he worked with his wife, Elisa Estes Ransom. In 1846, Ransom purchased a general store from his uncle, Jehiel Ransom, who had been in Niagara County since 1826 and served as postmaster. Ransom had 13 children and died at the age of 74 in Ransomville on December 29, 1889.

Ransomville was established as a farming community, but some of the earliest businesses were the log taverns built by Gideon Curtiss, the first of which was erected in 1817 and the second in 1825. A cemetery was laid out by 1821. In 1840 the Ransomville House was built as a larger, more refined building. In addition to the hotel, an 1860 map of the village lists two doctors and two blacksmiths, as well as a bootmaker, carriage maker, harness maker, grocer, lumber mill and general merchandise store.

Early settlers from the Curtiss family cleared and laid down the roads from Ransomville to Youngstown to the West (NY 93), along the ridge to the South (NY 104) and Lake Ontario to the North (CR 17). In 1876, The Rome, Watertown and Ogdensburg Railroad took over the Lake Ontario Shore Railroad and extended track, connecting Ransomville with Lewiston to the West and Syracuse to the East. This was later incorporated into the New York Central Railroad. A year later, Gilbert Curtiss built the Excelsior Elevator across from the rail depot. The Curtisses' agricultural business would grow to include a poultry farm that was considered the largest in the nation by the early 20th century.

In the 20th century, the town's claim to poultry fame faded with the development of new techniques and the opening of larger facilities. In 1924, the Volunteer Fire Company was formed with 24 charter members and Dr. John C. Plain as its president. A first fire hall was built in 1925 and then replaced by the current facility in 1960. Original equipment included a motorized chemical pumper rig, which replaced the hand-drawn cart. In 1933, Harold Bass opened the Bass Ford Dealership, which was soon joined by Richard Coulter's Chevrolet dealership. In 1954, Ed Ortiz and his brother opened the Ransomville Speedway for dirt track racing. The brothers moved the track outside of town to its current location in 1958.
