Botox in Guilderland, NY.

Guilderland was originally a part of the Manor of Rensselaerswyck that Patroon Kiliaen van Rensselaer began in 1629 as part of the New Netherland colony. By the end of the 17th century, Dutch settlers from Albany and Schenectady began to establish farms in the area, beginning first along the banks of the Normans Kill. In 1712, a group of emigrants from the Rhine Valley in present-day Germany passed through the town on their way to Schoharie. They were the first to record and name the Helderberg Escarpment, originally Hellebergh meaning “bright or clear mountain”. This name would also be used for all the land between the Normans Kill and the escarpment. In 1734, the first known religious service was held by a Lutheran dominie from Athens, New York to the “Normanskill Folk”, and the first religious structure was a Dutch Reformed Church in 1750.

Guilderland was, from its beginning, a location amenable to early industry due to its many streams for waterwheels, large forests for wood fuel, and the fine sand for glass works. In 1795, Jan and Leonard de Neufville (father and son) established a large glass factory mostly for the manufacture of windows but also for bottles of various shapes, sizes, and uses. Around this factory would spring up the hamlet of Hamilton (today called Guilderland). The factory could not compete with cheap British imports after the War of 1812, and with its collapse, the glass industry would never return to Guilderland. A hat factory and a foundry would both occupy the site over the next 200 years. French’s Mills, another hamlet founded on industry, was home to many textile mills, due to the power harnessed from the falls on the Normans Kill near Guilderland Center.

During the US Revolutionary War, many families in Guilderland were split in their loyalties. In New York, tenant farmers generally opposed their landlords, the Patroons, who sided with the rebellious independentists (Patriots), making New York one of the colonies where the war of Independence became a vicious civil war. The patroon of Rensselaerswyck and the local clergy, however, rallied the support of most of the local settlers in opposing the Loyalists. Those who remained loyal to the established government operated, among other places, from the caves of the Helderbergs, raiding settlements with the help of Native Americans. A battle between Loyalists and rebel Schenectady Militia with help from Rhode Island Continental Troops was fought just east of Guilderland Center. It was later alleged the local Loyalists were about to burn Schenectady and Albany, which is not entirely trustworthy as these would have been their own neighbors. In any case, the victory of the American forces allowed the Rhode Island contingent to travel to Saratoga for the Battle of Saratoga that occurred five weeks later, the turning point of the US Revolution.
