Although her crypt memorial reads like an ironic political statement about the famous queen who lost her head, a quick bit of research reveals Momo was a woman of French descent (her maiden name was Charbonneau and her mother's maiden name was Larievere) who married Earl, a man with an unfortunate-by-today's standards last name.
Momo lived in interesting etymology times. Dick is not only a longstanding geneaologically traceable surname, it was and is a common nickname for Richard, as well as a slang term for detective. But by the mid-20th Century it took on a vulgar twist, synonymous for man parts and contemptible jerks.
