The congregation I attended when I was a single JW sister, didn't have any single brothers, but there were several females. But when it became known there were several of age single females there were a few and I called them creepers come looking for a wife. None of my friends fell for them, fortunately. But before it was over most of us did eventually get married.
The first one of use to get married got married to the wrong man, they were divorced within less than 7 years.
The second one to get married met a brother originally from California who had temporarily transferred (work reason) to Kansas City Missouri. About a year after they were married they ended up moving back to where he was originally from.
The third one married a younger brother from the same congregation. He was about 3 years younger.. I believe that he wanted to marry someone like his mother because her personality and style of dress was just like his mother.
I was the next one to get married to my husband. We met at a kingdom hall build. He was from another state as well. I didn't know it at the time but he was a PIMO, but we had quite a lot in common. Our parents both became a JW to survive the big A in 1975 for starters.
This happened after I had moved away but another sister just couldn't find the right brother, and she ended up getting disfellowshipped twice for dating "worldly" men. When I last heard she had been married twice, and both times she married total dead beats who left her and their children without any support. She had to move back home until she could figure out what to do.
There were several others but I can't tell you what happened to them. As far as actual dating, there really wasn't. We all got married to the first guy we were "dating".
