Hit a brick wall With my family

Hello everyone , it seems I've hit a brick wall so to speak , in my Juarez and carrillo lineages . I've gotten as far as 9 generations in each. Family but now there's nothing left. For the Juarez sisde I found nothing from Felix olayo juarez and his wife justa rosa nabejas and fatter back in history. Same for Jose Maria Carrillo and gertrudis ortiz(Ortis). I found that they had 2 other children on new.familysearch.com but I can not find the records, hoping for names of grandparents. I'm stumped lol. Can anyone help me out or make any suggestions? Thank you all very much, Lorenzo Carrillo.
