Theresa Babb (1868-1948) was married to Charles Wilkes Babb (1-5-4-4-2-2-1-4), director of Knox Mill, Camden, Maine. For reasons unknown, she also possessed a gift for taking spontaneous and immediate photographs of her friends and family – such as these, while picnicking. Thanks to Marcus for bringing this collection to my attention!
