What is the meaning of the name Alastrine ?

Alastrine is Scottish in Origin.

Alastrine is a rare Gaelic feminine name from the Alexander family, formed as an anglicized counterpart to Irish Alastríona and Scottish Gaelic Alastrìona. These Gaelic forms developed from medieval Alastar/Alasdair, themselves adaptations of Greek Alexandros (alexo “to defend” + andros “man”). Accordingly, Alastrine carries the meaning “defender of men” or “protector of humankind.”

Sporadically attested in Gaelic-speaking communities and literary sources, the name surfaces in 19th–20th century records amid interest in cultural revival, but it has remained uncommon, offering a distinctive alternative to Alexandra and Alexandria. Variant spellings include Alastriona and Alastrina, with related masculine forms Alastair, Alasdair, and Alastar. Occasional nicknames such as Asta or Trina appear by preference rather than tradition, reflecting the name’s rarity and flexible modern usage.
