Seems to be derived from the masculine Greek name Anastasius, a latinized version of Anastasios, which means "resurrection". Its most famous holder is probably the Russian Grand Duchess Anastasia Nikolaevna, born in 1901, the youngest daughter to the last Tsar (Emperor) of Russia, and probably killed in 1918, when the Russian royal family was overthrown and killed. However, it is rumoured that she escaped, and the mystery around a possible escape has gone from rumour to legend and given way to several movies. There are several other people in history who hold this name, and some islands as well. So I can't say for sure, but the name probaby was originally a varrient of the greek name Anastasios, which means resurrection or revival. I hope this answers your question.
