Hello , to everyone in the group my name is Cecilia and I am starting my work on my family in
Jalostotitlan, not sure how to go about this and will appreciate any and all help and advice. my GG grandfather Jose Juan Olivar Married Maria Crescencia Padilla 1858 in SanJuan De Los Lagos . I have tried to get info from the LDS sight and find there is not a lot of info there and happened along your sight and hope for guidance in locating family tree in Mexico. I also don't know much about G grandfather Tomas
Villalobos and his wife Carmen De Los Santos. Thank You for any information on where and how to star by search in Mexico
