My family on both sides is very JW. My father was a Bethelite and a missionary. I was born abroad as a result. The religion has been one of the most dysfunctionally divisive forces of family destruction.
I was a Witness until I was 13 and most of my fam back in Brooklyn and Upstate are as well. Ironically, so is my ex girlfriend, and it's the reason she broke up with me. An off the cuff comment got me "Apostate'd".
I lived with my grandparents for 3 years and they were Baptists turned Jehovah Witnesses. Grandma did not hold to that claim but my grandfather did even though he never attended any meetings. His oldest son (my uncle) lived right up the road from us and his entire family was Witnesses that did make meetings. My 4 cousins and myself were very close, but today 2 of them are Pentecostal. I went that route also until I realized that I am atheist. You can blame too much bible study for that. :)
They are all dead now. Just myself and my 4 cousins survive.
My family is Pentecostal, so I grew up in that setting, however I did have a school colleague/friend (sort of) who was a Jehovah's Witness. She always tried to have me attend a church service with her, and would always bring pamphlets and booklets to school. How ironic that at the time I found her form of Xianity weird and "ungodly" lol
