Alter is both a surname and a given name. German and Jewish (Ashkenazic): distinguishing epithet for the older of two bearers of the same personal name. For the Ashkenazim: from the Yiddish personal name Alter, an inflected form of alt ('old').
Araceli is a somewhat obscure Spanish and Italian female name derived from the Latin elements “ara” meaning “altar” and “cælum” meaning “sky, heaven”.
