In 1859, she married Chilion Jones, the son of Jonas Jones, in Brockville; the couple had seven children. Shortly after their marriage, they moved to Ottawa where her husband, an architect, worked on the construction of the Parliament buildings. At the completion of that project, they returned to Brockville. Harvey operated a small dairy operation there. She began raising purebred Jersey cattle and established a large herd which she carefully managed. Taking advantage of the rich milk produced by these cattle, she began producing high quality butter which she was able to sell at a premium price in Canada and the United States. Her Canadian customers included the Rideau Club in Ottawa and the Canadian Pacific Railway.
