Ok I need help from the group. Can anyone help me find my grandfather
Antonio Cortez Hernandez….born in Matansas Jalisco the year 1909. His parents were Jose Refugio Cortez and Alejandra Hernandez.

I am also looking for my grandmother Ma Manuela Alvarado Ortiz born in 1913 also in Matansas Jalisco. Her parents were Lorenso Alvarado and Francisca Ortiz.

Antonio Cortez Hernandez was married to Ma Manuela Alvardo Ortiz.

I also have one more question. Can anyone give me advice on how to look for my uncle Eusebio Cortez Alvarado born in Matansas Jalisco. He was my fathers only brother and last I heard he lived in Gonzales Tamaulipas or Manuel Tamaulipas. I just need advice on how I can search for him. I have been looking for him for the past 3 years and have had not luck.
