Loren Latker, whose Shamus Town website is a great resource for anyone interested in Raymond Chandler and Los Angeles, has been doing some excellent research on Chandler’s early life and his family. His Chandler Timeline has just been updated with new material. Loren writes:
It now starts in 1858 with the birth of Morris, or Maurice, B Chandler. I’ve added many popup images for Ray’s birth certificate, his school records, a Laramie new item about an M Chandler attending a party in 1886, obits about his uncle Fitt’s brother and his aunt Francis Grace. I also found the document from 1927 where Ray started the process to regain his U.S. Citizenship. From that we learn that after WWI he returned to Canada, made is way to Victoria BC, boarded the Governor bound for San Francisco and arrived in March of 1919. He and Florence [Ray’s mother] were living at the West 12th Street address then. [Link to the Chandler Timeline]
