I do have a Maria Rosa LOPEZ in my file. She was born circa 1753 in Villa Sinaloa and died before 23 Nov 1828 (she is listed as difunta on her grandson's baptism record). She married Efigenio RUIZ circa 1769 in Alamos, Sonora. He was born circa 1747 in Villa del Fuerte and was buried in Santa Barbara County in 1795. Unfortunately, I do not have information on any of the other names you mentioned.
