Mary Charlotte Lloyd (23 January 1819 – 13 October 1896[1]) was a Welsh sculptor who studied with John Gibson in Rome and lived for decades with the well-known philosopher, animal welfare advocate, and feminist Frances Power Cobbe.

[2] Her father was a substantial squire over many counties, owning 4,300 acres of land, and Mary inherited money from a maiden aunt, Margaret, as well as gifts from Eleanor Charlotte Butler and Sarah Ponsonby, the Ladies of Llangollen.

[4] This allowed Lloyd to refer to herself as a landed proprietor when signing petitions supporting women's suffrage, and also gave her some local political rights, such as the ability to appoint a vicar.

[5] Lloyd died in 1896 from heart disease and was buried together with Frances Power Cobbe in Saint Illtud Church Cemetery, Llanelltyd.

Letters would be addressed to "you and Miss Lloyd" and Frances peppered her own writings with "our house", "our garden", "we" and other joint terminology.
