My major claim to fame was that I studied with a family that I found from house to house and all 6 got baptized. Within a year's time, the mom and daughter got baptized and then within the next year and a half all the others followed suit. 2 of the kids became Bethelites and the other daughter became an elder's wife. Her husband was a Bethelite too. The other young man is still an active JW. I also studied with lots of husbands and family members of JWs and they all, just about, got baptized too.
Most stayed in the religion and are diehard Witnesses. I'm sure these people are confused as to how I could EVER leave the Organization. I believe that the more entrenched Witnesses are with their families and friends, the harder it is to leave the cult.
