===Swain's Lock House===
[[Swains Lock]] House (Lock #21) is located in the eastern portion of the Travilah CDP in the Chesapeake and Ohio Canal National Historical Park. The lock and lock house were built in 1831.<ref name="Kelly213-214">{{harvnb|Kelly|Maryland-National Capital Park and Planning Commission|2011|pp=213–214}}</ref> The house is one of the largest canal lock houses, and made from oversized sandstone bricks. Jesse Swain was lock keeper beginning in 1907, and had been a canal boatman. His father (John) had helped with the canal construction, and his grandson (Fred) has lived in the house and operated an onsite concession stand into the 21st century.<ref name="Kelly213-214"/> At least two Swain children, and a cousin, were born in the house. The family lived in the house until 2006, when the National Park Service took over maintenance.<ref name="ConnectionSwains">{{cite news
