This video answers the question about why Lonnie left San Francisco and went South to Costa Mesa, eventually connecting with Chuck Smith. Unfortunately, the Jesus people of Haight Ashbury, who were based out of the Living Room on Page St while ministering in Haight Ashbury and in the House of Acts in Novato, where they lived, was broken up by false teaching.
You also have an account of why Lonnie partnered with Chuck Smith and you can see that the cult called the Children of God was dark from the start.
