I whanau a Alba i Pomona, California, ki a Catherine Louisa (née Jensen) me Mark David Alba. Ko tana whaea he Danish, Welsh, Tiamana, Ingarihi, me nga tupuna French, i whanau mai i California, he tamariki no nga manene Mexico. He teina tana, ko Hohua. Ko tana whanaunga tuatoru, i tangohia mai, ko Gustavo Arellano. Ko te mahi a tana papa Air Force i kawe i te whanau ki Biloxi, Mississippi, me Del Rio, Texas, i mua i te noho ki Claremont, California, i te mea e iwa ona tau. Kua whakaahuahia e Alba tona whanau hei "whanau tino rautaki <unk> he whanau tuku iho, Katorika, Latin American" me te tino liberal; e kii ana ia he "whawhai wahine" ia i te wa e rima. I te wa o te tamarikitanga o Alba i tohuhia e te tini o nga mate kino o te tinana, i whanau mai i California.
e whā ki te rima ngā wā i te tau
