I spoke to my mom (Olga Perrett) and she tells me that she does remember your grandfather Gamaliel. She tells me that she lived in the same ranch "El Recuerdo" as your grandfather when she was growing up. She also wants to know where your grandmother Oralia lives because she lost touch and would like to talk to her. Your grandfather Gamaliel was my grandfather's (Ambrosio aka Bocho)cousin. Sorry, it took me a while but I promise next time I'll post ASAP.
