  7. Ninfa, I just found out yesterday. I’m so sorry for your loss and my deepest condolences. As you know, Tivo and I grew up together on Alice street in Kingsville….so many fond memories. Just this past weekend, I ran into a picture with me, his brother Frank and Tivo from back in 1959. Let me know of his internment date.
    My sympathy,

      Thank so much for your condolences and your kind words. I know you will miss him. You have known him longer than I have, since you grew up together. We had a visitation and rosary at the funeral home this past Monday and a memorial mass yesterday at the catholic church we attend. His ashes will be buried at the veteran’s cemetery at a later date in San Antonio. We don’t have the date at this time. Thank you for reaching out to us at this difficult time. Jason and I really appreciate it.
