Fidencio R. Luna

Fidencio R. Luna, was married to Severa Campos Luna, Lived in El Paso Tex from 1900 to about 1937. They had 6 children, Castillo (TX), Concha (TX), Grace (CA), Fedencio (CA) Daniel (CA), David (AZ) Sometime after 1937 he moved to CA and was followed by some of his children. Am looking for his parents. I think this is his passport photo and think the R stands for Rodriques.
