Justa Arias Arias ("Mamá Justa")

Miguel's paternal great-grandmother. Mother of Anselmo Muñiz Arias ("Cheche", b. 1928, Miguel's paternal grandfather). Married Anselmo Fidelio Muñiz Romero (Cuban-Spanish Romero/Correa line, b. 1893 Puerto Plata) — per Ancestry GEDCOM S-004; Justa was one of his five recorded wives, hence the source-status caveat below.

The Arias-Arias compound apellido (same surname both sides) is documented in the GEDCOM and consistent with rural DR endogamy patterns.

Connected to the Lithgow-Ceara line via documented lifelong friendship with Baudilia Rosalía Ceara Díaz — see justa-baudilia-friendship-annie-narration.
