Beltran-Ramirez-Curiel / Flores-Alvares

I'm researching my ancestors, I am not an advanced geneologist by any means and any help would be greatly appreciated. My maternal grandfather is Julian Beltran Ramirez, his parents were Francisco Beltran and Aniceta Ramirez Curiel. In the 1930 Census it lists my grandfather as having been born in Juanacatlan, Jalisco in 1910 and his father from La Cofradia, Jalisco in 1874 and his mother from Zaplotanejo, Jalisco in 1875. I am looking for dates and information(birth, death, etc) for their parents. Eduviges Beltran and Francisca Navarro. I only have their names but I can't find any dates for them or where exactly they are from.

My maternal grandmother is Gregoria Flores Alvares born in 1915 and her parents Marcelino Flores born in 1890 and Simona Alvares born in 1900. In the 1930 census it just lists all of them as being from Jalisco, Mexico.

Thanks in advance for any help.
