DEAR MISS MANNERS: How do you address a formal invitation to a married lesbian couple who have the same last name? For example: Lisa Jones and Maggie Jones. Do you write Mrs. and Mrs. Jones? Or Mss. (plural of Ms.) Jones? Or Ms. Lisa Jones and Ms. Maggie Jones?
GENTLE READER: Having lost the grammatical battle of "they/them" -- she is entirely in favor of a nonbinary pronoun, if not the sometimes-confusing plural -- Miss Manners is determined to get ahead of new honorifics.
She will spare you the history lessons about Mrs. being short for Mistress -- which eventually took on nefarious tones, as so many female monikers do -- and about Ms. being historically correct centuries ago, not just a 20th-century feminist invention.
Oh, look at that: She did not spare you the lecture after all.
She therefore humbly suggests: "the Mses Jones."
Lest you retort that Ms. is not for married ladies, it is. It just does not define a woman as married or not. That ought to quell all of those other rightful patriarchal objections.
With this particular surname, you could also just say "the Joneses," but she begs you to resist "the Mses Joneses," as fun as it might be to say.
