Thank you very much for the detailed information on how the original rancho
de Joan de Angon (1633) became Estancia Rio Chico in 1681 and finally
changed to Hacienda Santa Rosa. I presently do not have any pictures of Rio
Chico/Hacienda Santa Rosa. I researched a location for a Rio Chico and
found it to be about 37 km (23 miles) from Teocaltiche. This location is
significant to me because it suggests that a child could be born in Rio
Chico and baptized in Teocaltiche. This is the pattern that my ancestors
followed. In 1752 Juana Maria Lozano Diaz was born in Rio Chico and
baptized in Teocaltiche. She was the daughter of Juan Miguel Lozano
(generation 9) and Lorensa Diaz de Sandi. Juan Miguel is also the father of
Rafael Lozano (gen. 8, b. abt. 1740), who married Petra Aguilar. Rafael had
a son also named Juan Miguel (gen. 7, b. abt. 1765), who married Maria
Tejeda about 1799. One of their sons is Domingo Lozano (gen. 6, b. 1816)
who married Paula Becerra in 1839. His oldest child was Eugenio Lozano
(gen. 5) who was born 17 Nov 1841 in Rio Chico. Eugenio left Teocaltiche
and went north to El Paso, Texas. He is my great-great grandfather.

I have to look up the church records for those ancestors between Eugenio and
Juana Maria Lozano Diaz, to see if there is continuity in their being born
in Rio Chico. If Eugenio was born there, your information suggests that it
may be another Rio Chico since it is not listed as Santa Rosa. Thank you
again for your valuable input, I will continue this research and keep
everyone posted.
