Mar,ܡܪܝ meaning "father" in Syriac. A title of address for prelates of the Assyrian Church of the East, Syriac Orthodox Church, Syro-Malabar Church, Chaldean Catholic Church and the Syro-Malankara Catholic Church.
It can also be the title of a Saint, for example "Mar Toma" or "Mar Thoma" = Saint Thomas.
Also derived from the same Aramaic word, Mar was the title of the Exilarch (Reish Galuta), the head of the Jewish Community in Babylon which enjoyed considerable authonomy.
Derived from the above, Mar in modern Hebrew as spoken in Israel is the equivalent of "Mr.". Though there is no etymological connection, similarity with the English term helped its spread.
Martha was originally the female form of the same, "ta" or "tha" being the Aramaic ending of female nouns. The Biblical character of that name was "The Lady" in Aramaic, and her being a saint made it a widespread female first name in Christian countries and cultures.
