As a child I remember a Gilbert who was a cousin to my mom Lupita Martinez, then married and was Lupita Sandoval, later remarried and was Lupita Reyes. Gilbert had a severe curvature of the spine and a pronounced limp. I believe he was a widower with children and lived in San Francisco and died. That is all I know of this Gilbert and truly am not sure if his last name was Alire. Our family name does not have an S at the end. Good luck. We have many relatives of Alire, Martinez, Lucero, Sandoval, Garduno last names.
