Encarnacion Calvillo & Ysidora Ramires

I have established that Eugenio Calvillo, my great-grandfather, was a son to Encarnacion Calvillo & Ysidora Ramires. This information is based on Mormon Church archives for the San Jose Parish in Calvillo, Aguascalientes,Mex. Eugenio is listed as being christen in 1840. Eugenio married Filomena Mungia from Reynosa, Mex. in 1877 in Hidalgo County, Texas. I do not know if Eugenio was an only child.

I would appreciate any information on Encarnacion Calvillo or Ysidora Ramires.
