Sorry to have taken so long in answering your last post.
My grandmother, Antonia (Mendoza) Bates was born in Durango, Durango on July 25th in either 1891, 1895 or 1898. I lean more towards 1891. Her brother was Jose Maria de Jesus Mendoza who was born May 9, 1889.
Antonia was enrolled at a private Catholic school in Texas in 1906. Her brother Jose graduated from Notre Dame in 1910. In both of their transcripts, the guardian/parent is given as Bishop Obispo N. P. Gavilan. Their parents names were never known until I found Jose's baptismal certificate. I have yet to find Antonia's baptismal cert. I am 95% confident that the baptismal certificate I found of Jose's is the Jose Mendoza I was looking for, as it was dated on his birthday and came from the particular church I believe his family attended.
I researched Bishop Gavilan and found that from Feb. 20, 1902 to Dec. 3, 1919 the Bishop of Chihuahua was Bishop Nicolas Perez Gavilan Echeverria. This begs the question; Why use the Bishops name as guardian instead of the parents?
It has always been the belief of my fathers family that my Mexican grandparents were probably assasinated by the revolutionary forces, particularly Pancho Villa's army.
At this point, this is all the info I have. I don't really know where to go from here. Do you have any suggestions?
