A creek running through the community was named after Major Stillman of the Illinois Militia who on May 14, 1832 led troops in what became the first named battle of the Black Hawk War. The battle and the creek were called "Stillman's Run" after Stillman and his men fled the battlefield in the belief that they had been attacked by a superior force of Chief Black Hawk's warriors. The day after the battle, Abraham Lincoln was with the militia who buried the dead soldiers from the battle. The village was named after Stillman Creek; the valley serves as the watershed for the creek, hence the name Stillman Valley. The Stillman's Run Battle Site and burial ground are in present-day Stillman Valley. A large memorial to this battle was erected in 1901. It reads, in part: "Here, on May 14, 1832, the first engagement of the Black Hawk War took place. When 275 Illinois militiamen under Maj. Isaiah Stillman were put to flight by Black Hawk and his warriors." Demographics As of the census of 2000, there were 1,048 people, 395 households, and 295 families residing in the village.
