Harriet Campbell was born in 1786 into a family of United Empire Loyalists to Charlotte (née Saxton) and Archibald Campbell Sr, a merchant in the timber trade. The family migrated to Nova Scotia following the American Revolution, moving to Quebec in 1790 where they prospered and became well known in the city. One brother, John Saxton Campbell became a merchant and seigneur, another brother, Archibald Campbell Jnr, was a successful lawyer. Her sister Louisa Sophia married politician Jonathan Wurtele.
In 1809, Harriet Campbell married William Sheppard, a merchant in the same timber trade as her family. They had seven children, but only Charles Campbell, Charlotte, William and Maxfield lived to adulthood. Charlotte married politician Robert Nugent Watts and had a son William John Watts.
The couple bought a property of 100 acres in Sillery in 1816, naming it “Woodfield”. They installed a library with 3,000 books, as well as a gallery and a natural history museum. They added greenhouses, transformed the gardens and built aviaries which housed an European Linnet and a Serin, alongside birds indigenous to North America, particularly ones with beautiful songs or attractive colourings.
Work in natural history
She was noted for studying and publishing on birds, shells, and plants of the Quebec region. Working with Anne Mary Perceval and Christian Ramsay (Lady Dalhousie) she collected plants of the region. Along with Perceval, Ramsay, and Mary Brenton, she was a contributor to William Jackson Hooker’s Flora boreali-Americana (1829–1840). The three women provided 80% of the information relating to Quebec in the publication.
Her first publication was in 1829, in a paper On recent shells which characterize Quebec and its environs in the proceedings of the Société pour l’encouragement des sciences et d’arts en Canada.
