Alastriannah is a rare modern elaboration built on the Irish and Scottish Gaelic Alastríona/Alastrìona, the feminine counterpart to Alastar/Alasdair (Alexander). Through Greek Alexandros (alexein “to defend” + anēr “man”), its core meaning is “defender of humankind.” The -annah ending aligns it with the enduring Anna/Hannah family, giving the name a familiar cadence while keeping its Gaelic spine. Usage appears almost exclusively in 21st‑century Anglophone contexts, with no attested historical bearers, reflecting contemporary tastes for ornamented, multicultural forms.

Common variant spellings include Alastrianna, Alastriana, Alastryanna, and Alastrionna; closely related names are Alastríona/Alastriona, Alexandra, Alessandra, and Alexandra’s Celtic forms. Possible diminutives are Ali/Allie, Astra, Tria/Triana, Ria, and Anna/Annie. Parents drawn to Alastriannah often seek a distinctive, lyrical alternative to Alexandra that nods to Gaelic tradition while preserving the protective meaning.
