Alastrinah as a Baby Name. Meaning and Origin of Alastrinah

What is the meaning of the name Alastrinah ?

The baby name Alastrinah is a Female name , 4 syllables long and is pronounced ah-LAS-tree-nah (IPA: /əˈlæstriːnə/).

Alastrinah is Irish, Scottish in Origin.

Alastrinah is a modern elaboration with Gaelic flavor, likely shaped by the Scottish and Irish Gaelic feminine name Alastrìona/Alastríona, themselves cognate with Alexandrina and Alexandra. Through this line it traces back to Greek Alexandros (aléxein “to defend” + anḗr/andros “man”), yielding the meaning “defender of humankind” or “protector.” The -h ending follows contemporary English stylistic trends rather than a traditional Gaelic spelling, while preserving the lilting a-LAS-tree-nah rhythm.

Documented usage is very rare and contemporary; the form appears in late 20th–21st century baby-name discussions and occasional Anglophone naming. Close variants include Alastrina, Alastriona, and the accent-marked Alastrìona (Scottish Gaelic) and Alastríona (Irish). Related names include Alastair/Alasdair (Gaelic masculine), Alexandra, Alexandrina, and Alessandra. The name appeals to those seeking a romantic, Celtic-leaning alternative to Alexandra while retaining the classic “defender” sense.
