Hi Leolaia,
According to William P. Heath Jr.'s testimony at the Moyle trial (pg 1259) he became a JW in 1932. Before that he said the he didn't belong to any organized religion, though he claimed to have attended many churches (pg 1295). Also of interest is the fact that Heath's mother was also a JW. She originally became a Bible Student in 1915. Heath first became aquainted with Rutherford in 1934. Heath married Bonnie in Las Vega, Nevada in 1938.
Page 1296 of the transcripts has some very interesting material. Moyle's attorney Walter Bruchhausen questions William Heath Jr.
Q. By the way, was there any particular reason for getting married in Nevada?
Heath: No.
Q. Had you been divorced?
Heath: Yes.
Q. How long had you been divorced before you married in Nevada?
Heath: Oh, just a short time.
Q. How short?
Heath: Beg pardon?
Q. How short?
Heath: I think about a week.
It is very intersting that Heath was granted a divorce from his first wife in Nevada and then married Bonnie the following week in the same state. Quickie divorces were legal in Nevada and probably it is still legal there today. Therefore, Heath was still married to his first wife when he went to Bethel in 1937. JFR not only knew of Heath's marital status when he added him to his intimate circle, but also approved of Heath's quickie divorce. Such divorces were very common among the Hollywood set, but were quickie divorces and remarriages common among the rank and file JWs of that era? I don't think so.
Unfortunately Moyle's attorney didn't ask Heath about the grounds for the divorce. However, the circumstances surrounding Heath's divorce makes me think that he got what the JWs today would call an "un-Scriptural divorce."
