I couldn't find an obit for Julia. The first George was married to a lady whos ename wasn't Julia. The second one may not be the right one either. He had a very short obit:
George Houston Cartwright, 83, of Ceres died yesterday in a local nursing home after a brief illness. Services are pending at the Shannon and Carmody Funeral Chapel. A native of Illinois, Cartwright had lived in California for 41 years. He was the father of Harvey Cartwright of Ceres.
