    I am so sorry for your loss. Your dad was a great man. I am so grateful to have known him and so grateful that he allowed me to be a part of your family. Will forever remember the trips in the banana van. He will be deeply missed, may your dad rest in peace with our Lord Jesus Christ🙏

  6. I remember spending a lot of time with my best friend Patricia and loved spending time with her brothers Oscar and Sammy and Mom and Dad. Mr Mancillas was quiet but Stoic and we Girls probably drove him crazy with our laughing and silliness. But you couldn’t tell because He was always so friendly. He was kind and invited me with family on a trip to Slide Rock, which I’ll always remember. Rest in Peace Mr Mancillas!

  7. Daddy. Me and the kiddos miss you so much. We thought we had more time with you. But you left us to soon, I know your not suffering anymore and I hated seeing you like that. I really hoped you had more time to spend with Reina, Pancho and your other grandchildren. Whenever I go over to be with mom the house isn’t the same anymore with you not there. I know you’re in good hands now with our Lord Jesus Christ until we meet again. I love you daddy ❤️
