i just found a jose maria rubalcava married to maria apolinar lopez. they are my gg-mother (eleuteria rubalcava b. abt. 1820-1840)) parents and they are from sabinas hildalgo. does anyone know if sabinas hidalgo is intamaulipas or nuevo leon? i also found eleuteria has a brother name julian rubalcava. he appears in a lot of documents but i'm at a dead end with the parents.
