It is also near the intersection of Arkansas 16 and Arkansas 27. Tilly has a general store that was established in 1939 by Alfred & Avis Fountain. The store has a local post office branch located within. The cemetery located in Tilly is the "Union Hill Cemetery" and has a cemetery building adjacent to the cemetery.
In January 1996, Tilly was the scene of a triple murder, when gun dealer William Mueller, his wife, Nancy, and their eight-year-old daughter, Sarah, were abducted, tortured, and murdered in their own home by white supremacists Chevie Kehoe and Daniel Lewis Lee. Kehoe later received a life sentence for the crime, while Lee was sentenced to death and executed.
