Hello, I am trying to find my paternal grandfather's line in Distrito Federal, Mexico or otherwise known as Mexico City.

My grandfather rarely talked about his family and now that he has past away I have no way of gathering more info.

My grandfather, Alberto Meneses, was born in 1917 in Tacuba, Mexico which is a county within Mexico City. His parents are Cirilo Meneses and Jesus Lopez. I found my grand uncle in church records, but can't seem to find my grandfather or the parents' name of Cirilo and Jesus.

Help or hints would be much appreciated. Thanks!
