Biblical name, borne by the mother of the prophet Samuel (1 Samuel 1:2), Hebrew Hanna. It is derived from a Hebrew word meaning ‘He (i.e. God) has favoured me (i.e. with a child)’. See also Anne. This form of the name was taken up as a given name by the Puritans in the 16th and 17th centuries and remained popular until the late 19th century. Thereafter it fell somewhat from favour but has enjoyed a massive revival since the 1990s.
English: from Middle English more ‘moor’, ‘marsh’, ‘fen’, ‘area of uncultivated land’ (Old English mōr), hence a topographic name for someone who lived in such a place or a habitational name from any of the various places named with this word, as for example Moore in Cheshire or More in Shropshire.
