In 1812, Billings moved to the Ottawa area and settled on a farm south of the Rideau River in what was then the Township of Gloucester.
In 1830, a bridge was built over the Rideau River near the Billings Farm to make it easier to transport produce into town.
The couple's oldest son, Major Bradish Billings II (1847–1891), a pupil of architect Henry A. Sims in Philadelphia from 1863–1866, opened an architecture office in Ottawa in 1870 and later worked as a public servant with the Interior Department 1872-1885.
The City of Ottawa owns and operates the former Billings family homestead as a museum and park located on over 8 acres (32,000 m2) in Alta Vista.
The museum runs numerous programs for families throughout the year and operates a tea service on the lawn in the back gardens from May through August.
