She is chiefly noted for her watercolor drawings of the Giant's Causeway in County Antrim, which brought international attention to the site.

A work entitled ‘One Tree Hill, Greenwich Park’ (signed and dated 1733) suggests that she received instruction and lived in London around this time.

Her drawings are composed of gouache on vellum and present two views of the Causeway from the east and west.

These paintings show accurate details of the jointing forming the basalt columns of the Causeway.
