Named for William Darne, the community was built on 2,000 acres (810 ha) of land inherited by his wife from her father Charles Gassway's 'Mount Pleasant' land grant. Originally, the town was referred to as Mount Pleasant, but the name shifted in popular parlance to Darne and eventually Darnestown. The community was located halfway between Montgomery Court House (modern-day Rockville) and the mouth of the Monocacy River, and originally consisted of a tavern, a pair of blacksmiths, a wheelwright, a single store, and a log building which served as both a school and the home of several churches. The community's greatest economic boom was during the Civil War, when providing for the needs of the armies camped around Washington, DC provided new income. Following the war, however, Darnestown slowly deflated and eventually ceased being a commercial center, with only a few of the original buildings left standing. The area has since been absorbed by suburban development.
Darnestown is home to the Seneca Academy, a private school for grades Kindergarten-5. It is also home to Darnestown Elementary School and Jones Lane Elementary School, part of Montgomery County Public Schools. Though Quince Orchard High School is within several miles of most of Darnestown, all residents who are in the Darnestown Elementary School District lines will attend Northwest High School in Germantown instead. Jones Lane Elementary School students do attend Quince Orchard High School. Mary of Nazareth Catholic School, Seneca Academy, and Butler Montessori School are K-8 private schools that are in Darnestown.
Darnestown has a small commercial center with a few businesses, a Harris Teeter, and a gas station.
