I have recently discovered that my great-great grandparents were: ESTEBAN MONTEMAYOR and JUANA LOZANO. They had at least one child that I know of: ADELA MONTEMAYOR who was born around 1891 and married JOSE AURELIO MARTINEZ on May 16, 1907 in Marin, Nuevo Leon. ADELA died in Texas in 1955.
If anyone has a connection to this family, I would love to hear from you. Thanks.
