Many, now that this thread made me think back.
Not just elders though, some were servants, serving where the need was supposedly greater.
One cold Book Study overseer, quite judgmental it seemed, turned out to be having a 2 year affair with a servant's wife. When it was found out, he was disfellowshipped. She was not as I recall, because she was just reinstated and this was one of the brothers on her committee.
Another was not disfellowshipped but was temporarily removed. I don't know the details other than he, among other elders on the same body, were giving terrible "unscriptural" advice to a sister who was having problems with her husband. What bothered me about this one elder was he often had some kind of sleazy look on his face and he was a chauvinist. So sometimes he was quite affectionate, but other times he was disrespectful toward women. It was strange and uncomfortable. He was dishonest in his real estate practices too. Took commissions after escrow closed, that kind of thing.
Another was molesting his two stepdaughters for about 10 years, part of this time serving where "the need was greater", being a big shot. When one of the girls reported it, the other came forward too. So he was reproved. But years later, when the younger girl became engaged, she felt her fiance was entitled to know what she had been through and that she was damaged from it. So he approached the stepfather's current body and told. Nothing happened to the former molester, but the mother of these girls was enraged at the daughter who had told her fiance, and swung her fist at the girl, hit her hard in the face and knocked her down, threw her out of the house and screamed at her that she should have kept it quiet, and told her never to come back to the house.
Another elder molested his stepdaughter for many years while an elder. When it came out, he was removed, disfellowshipped. His stepdaughter is damaged but she has a good relationship with the man now. It's her mother who's everyone's nightmare. The fact that this woman stayed with him after, just to make his life hell after the truth came out, was the hardest part. Well not really, and I don't at all excuse him or respect him regardless that he seems to have completely changed, never doing that kind of thing again, by all accounts. It's just hard to see anyone live with a crazy woman who keeps telling anyone and everyone, "he did this, so now, he owes me, and it's all about money now." This man did a hideous thing and I never warmed up to him but I have to say, after it was all said and done, he always behaved like a dignified and kind person, putting up with anything his wife did or said for years after the terrible act. All their other kids are so nice, kind, dignified men. Odd.
Another elder I really feel for. Totally nice person, fun, cool, highly intelligent and creative. His answering machine messages were out of this world amusing. He had been a bomber pilot in a war, and was plagued with memories of people he had bombed. Says he saw some after his bomb had hit. I don't know anything about that but I felt for him. He was married to a very troubled, cold sister, who would harangue the kids constantly, and browbeat her husband too, saying things like "I wasn't supposed to have to be with you this long!! You were supposed to die in the war and leave me a widow. And you came back instead." Well, she tried to kill herself a couple of times and was reproved for it. He eventually started a relationship with a non-witness; I believe she was his Bible study. He was disfellowshipped and he moved in with her. He and his first wife got divorced and he married the normal, sane lady. And was then as happy as he could be. He was kind of haunted.
Another elder, one of the little stars of the circuit, constantly giving talks on the assemblies with his picture perfect little family, was found out for having a years-long affair with the other darling of the circuit, the lovely regular pioneer wife of the Presiding Overseer of another congregation. I felt for her but detested the brother who took her that way. They were both df'd and she was so humble about it it made me ill. I would talk to her at work, about work, and she would hang her head and whisper, "I'm df'd." I said, "And? So?" But kindly, because I felt for her. Anyone who could be attracted to THAT guy had to need affection very badly. YUCK.
Enough for now.
