ALEXANDER (m): The Latinized form of Greek ALEXANDROS (an alternate name of Paris, Prince of Troy). The name owes its popularity, however, to the brilliant Alexander III the Great, King of Macedon (356-323 B.C., ruled from 336), who conquered most of the then-known world in 13 years.
ALEXANDRA (f): The female equivalent of ALEXANDER. It became especially popular in Britain with the marriage in 1863 of Albert Edward, Prince of Wales, to the very beautiful, very forbearing Alexandra of Denmark (1844-1925, Queen Consort 1901-1910).
SANDY (m): Scottish nickname for ALEXANDER, from which the surnames SANDERS, SANDERSON, etc. are also derived.
SANDY, SANDI (f): Popular current nickname for SANDRA, a shortening of ALEXANDRA.
