Guilderland's farms followed the Normans Kill before the town did
The land that became Guilderland was part of the 1629 Rensselaerswyck patroonship, and Dutch families from Albany and Schenectady were farming along the Normans Kill by the late 1600s -- more than a century before the town incorporated on February 26, 1803, splitting off from the Town of Watervliet. Lieutenant Governor Jeremiah Van Rensselaer suggested the new town's name, after Gelderland, his family's home province in the Netherlands.
What that farmland-to-suburb timeline means for water lines
A property near the Normans Kill or one of Guilderland's older farm-era roads can still carry a well or a supply line installed long before the surrounding area filled in with 20th-century development, while a newer subdivision nearby is on an entirely different generation of plumbing. Knowing which era a given Guilderland home falls into changes what a plumber should expect to find underground.

Before the conversation
If your property is on well water or an older section of town, mention that up front. Note when symptoms started and whether they track with weather or water use elsewhere in the house.
