I had searched for a picture of Mary Buckland while preparing a presentation for the 125th Annual Meeting of the Geological Society of America. I was asked to make a presentation in the "Great Books" session, and I chose to present on William Buckland's Bridgewater Treatise (1826). Except that I called it "William and Mary Morland Buckland's Bridgewater Treatise" because Mary Buckland (nee Morland) was an important partner in Buckland's works, including illustrating, editing, and general partnership in all things paleontological. She was already a practicing paleontologist (though that label wasn't yet used) when she met William Buckland, marrying him about 5 years later.

Finally, a few days before GSA, I found a photo portrait of Mary Buckland. She looks to be in her later years. She bore 9 children, five of whom survived to adulthood. She home-schooled them. She partnered with William Buckland in his paleontological works and did large illustrations for his Oxford lectures. So here is the only known picture of Mary Buckland:
