My mother is still an active JW. She turned 85 back in May. Her mother was a JW, and two of her sisters are, as well as several of her nieces. My dad was in for a short period, but he did that mostly to try and hold the marriage together and it didn't work, so he left both the organization and the home back in the 80s. He passed away in 2001. One of his sisters is still a JW, as far as I know. She would be in her 80s as well. I doubt her sons are still JWs, they did not seem like the type to stay, heh.
My sisters and I are all out, we either left or faded over a long period of time. My older sister was a regular pioneer for a few years before she left (I later learned that she pioneered on the advice of some elders to deal with some issue she was having- it didn't work). I was a ministerial servant for about a year in the mid-90s. It felt like the culmination of a lot of hard work to get there, but by then my heart really wasn't in it and I lost that 'privilege' and that accelerated my fade (though I would never have thought I was fading at the time).
