MRS-MRS. (the last two letters are properly in lower case) D (are you the wife of Mrs. D?),
Only very important men, such as the Exilarch (Reish Galuta) were called “Mar’ (according to the Sepharadim “Mor”) or “Abba”. Sometimes women were called “Ima” (“Marat”, not “Mara” is relatively recent) but it was rare. For example, Rav Nachman’s wife, who was also the daughter of the Reish Galuta and a very aristocratic and opinionated (see Berachot 51b – and note how Ulla responded to her) woman was called by her name, Yalta.”Beito” or in Aramaic “Beitei” (not “Bayit”) was used in the third person (e.g. “beito shel Rav Ploni).
When people call me “Mar” I respond that I am not mar, I am matok. When they call me “Rav” I respond “Ani lo rav im af echad”. One person sometimes calls me “Chacham Avraham” – generally when he wants something.
You’re welcome very much.
