This thread has been really helpful. I am doing a wee bit of research into women who owned and managed quarries and Rebecca Hutchison (nee Pearson 1842-?) was such a woman. Her family lived in the Galloway Lodge, Powburn, handily shown on the map linked above. Without that link I would not have known how to find a map like that for such a specific place.
Her mother was widowed in the late 1860s and seems to have continued her late husband's stone contracting business until the children, Rebecca and David took it over. They ran the quarry at Ratho until at least the 1890s but I am not sure after that, although it finally closed in the 1920s.
If anyone here wants more about them just let me know.
