Between 1788 and 1793, the townships at the Head-of-the-Lake were surveyed and named. The area was first known as The Head-of-the-Lake for its location at the western end of Lake Ontario. John Ryckman, born in Barton township (where present day downtown Hamilton is), described the area in 1803 as he remembered it: "The city in 1803 was all forest. The shores of the bay were difficult to reach or see because they were hidden by a thick, almost impenetrable mass of trees and undergrowth ... Bears ate pigs, so settlers warred on bears. Wolves gobbled sheep and geese, so they hunted and trapped wolves. They also held organized raids on rattlesnakes on the mountainside. There was plenty of game. Many a time have I seen a deer jump the fence into my back yard, and there were millions of pigeons which we clubbed as they flew low."
George Hamilton, a settler and local politician, established a town site in the northern portion of Barton Township in 1815.
