What is the Address for author Robert Franklin Leslie?

Hi, Bob Leslie was my neighbor in the 1970's in Camarillo California. At that time he lived on Coe St. He suffered a stroke in the early 80's, and I lost touch with him. He and his wife, Lea, didn't have any children, but he had a nephew who came in to help once he had his stroke. I'm sure he moved from Camarillo after his stroke. He was in his 70's when I knew him, so it's possible that he is no longer with us. He was such an amazing man. Joi Hayden
