Hello Murray,
My name is Robbie Isner, my father is Robie Isner. I was talking to my dad about your message, and he says that the Robie Isner you are wondering about is his uncle. My dad says that uncle Robie got sick and died of liver failure in New Mexico in 1948.Robie was a harness race driver and was in New Mexico Racing horses at the time. My dad says that you and him are 2nd cousins, and if you would like to call him about uncle Robie he would be glad to talk to you.
