The area was first settled by Henry Rhodes after obtaining a land grant in 1841 of about 1000 acres (4 km²) from the Republic of Texas. The name, however, comes from a later settler, John Grey Jolly, who purchased 160 acres (0.6 km²) in 1866. John and his wife, Nancy Isabell Jolly, operated a blacksmith shop and store. The Jollys donated land for a school and the cemetery in which they were eventually buried. Jollyville remained lightly settled for decades; only twenty families lived in the area in 1960. Eventually, the growth of nearby Austin led to the development of Jollyville as a suburban community.
The bulk of what is generally meant by Jollyville is an unincorporated area of southwest Williamson county. Although Jollyville has appeared on maps since the late 19th century, it is not a legal entity. Parts of what can be considered Jollyville lie in both Williamson and Travis counties and both within and outside northwest Austin. The United States Census Bureau's definition of Jollyville as a census-designated place lies entirely outside of Austin.
Jollyville is located at 30°27'12" North, 97°45'45" West (30.453288, -97.762381).
