Wow, good find, so now she's there, now she's not.....
Joe Wilson has done an Orwellian memory-hole for his 2nd wife in "Who's Who"..... now why would he do that?
Maybe the current wife didn't want any trace of wife #2 in the entry...wife #1 stayed because she was the mother of his two older children, I suppose. There wasn't much of an interval between divorce #1 and marriage #2. Because the second marriage is ignored in the 1999 ed. and later, we can't tell how long the interval was between divorce #2 and marriage #3, but it probably was short. At any rate there doesn't seem to be time for any other ex-wives, unless there was a brief marriage before Susan Dale Otchis (but he was only 23 when he married her).
I tried to post the entry from the 1998 ed. as a new thread but it didn't take...I'm not sure what I did wrong or if there are others who have been trying to find the name of ex #2 (but may not read this thread).
