Founding of Saybrook
Saybrook was laid out March 4, 1856 by Isaac M. Polk (c.1814–?). Not much is known about Polk. He was born in Indiana and does not seem to have lived in McLean County for very long. In 1860 and 1870 he was in neighboring Livingston County. Saybrook is the only town in McLean County on the banks of a major river and the uppermost town on the Sangamon River. The woodland along the Sangamon, which became known as Cheney’s Grove, attracted early settlers. Jonathan Cheney had come to this area in 1825 and built a cabin across the river from the later location of the town. In 1833 Robert Cunningham built a water driven mill on the Sangamon; it was later replaced by a steam driven mill. In 1857 the town consisted of a saw mill, a blacksmith shop, a carpenter shop, one store, and eight dwellings. The total population was twenty-one. The township in which the town was situated was named took its name from the woodland and was called Cheney’s Grove. The name Saybrook was adopted in 1865, likely by settlers that came from Old Saybrook, Connecticut.
Original Town Plan and Development
The Original Town of Saybrook was one of the smallest in McLean County. It consisted of a simple square of four blocks, each block containing eight lots. This original plat had been laid out over a series of road and lot lines which were aligned at roughly forty-five degrees to the first official town plat; some of these old lines, shown in dashed markings, can been seen on the 1856 plat. The original town had no square or other distinguishing features. In 1866 the Town Council laid out a large addition north and east of town. This was said to have been done to make the town look as large as possible to railroad promoters. This seems unlikely. As will be seen, Saybrook was well known to many of the men associated with the founding of the railroad. The town of Saybrook was incorporated May 29, 1866.
Bending the Railroad
One thing clearly evident to the citizens of the fledgling town: it would only flourish if a railroad could be attracted. The most likely railroad was the one which would later become the Lake Erie and Western. It would be built run due west from Bloomington to Paxton in neighboring Ford County and, because of this, would probably miss Saybrook by several miles. At this point the three Cheney brothers, sons of Jonathan Cheney, mentioned above, entered the picture. Haines Cheney, then in the Illinois Senate had arranged for the charter of the road. To fund the railroad, local towns and townships would issue bonds, which the taxpayers would eventually retire. Two other Cheney brothers, Jonathan H. Cheney and William H. Cheney - who was the second largest landowner in Cheney’s Grove Township - became members of the railroad’s Board of Directors. William H. Riggs, the supervisor of Cheney’ Grove Township, was also on the board. Cheney’s Grove Township voted to fund $50,000 in bonds and the Town of Saybrook added an additional $10,000 in bonds. With this kind of backing, the route of the road was deflected and it passed through the town. In November 1871, when the tracks reached the village limits of Saybrook, a great celebration was held. A bottle of champagne was produced, but rather than smash the bottle, the thrifty reception committee simply knocked off its neck so the contents could be consumed later. The new Christian church in Saybrook invited visitors from Bloomington to attend their first service and announced that there would be a special train “on our railroad.” 
After the Railroad
Once the railroad was established in 1870 Saybrook grew rapidly. It soon became the largest grain shipping point in eastern McLean County. A depot with depot grounds was established just south of the Original Town. In 1870 Thomas Holloway built the large brick Union House Hotel. In 1872 a newspaper was established. There was a boom in the construction of houses and stores. By 1900 there were 879 people in the town. In the twentieth century the population of Saybrook declined by about fifteen percent. By 2000 Saybrook was smaller than it had been a century before.
