My mom came in because a JW woman who went to their door when she was a baby told my grandma that she would take her to church a few times a week to give her a break with her new baby. When the next new baby came, she brought my uncle, also. So, my mom went on the JW "church bus" from infancy (she was about a year old). Her mom never joined but went to some meetings. Her brother did join. My mom brought ONE person in that she knows of. Her next door neighbor/best friend (not through d2d service unless coffee morning gossip counts). My mom has no JW kids ever baptised. One friend-who got her husband (now an elder) and one kid out of two (also an elder, I think) in. I don' know their stats, but my mom, as much as she hates it, has been goin out in service regularly since she was baptised (well after 30) No suckers other than the neighbor to her credit and the neighbor was baptised before my mom was, so she probably doesn't even get credit for it. One of her sisters eventually gave in to family pressure (myriad family crises) and joined, left, joined, left, joined (ad infinitum) and now is a pioneer () The one brother, was totally a mess before he died. So, not one JW kid (or ex-none of the ex spouses are still JW). Just my mom and her sister. there may be a few shirttail relatives that still go to memorials, but none joined as a result of my mom though some did join. They are a whole other kettle of fish and the one that is still in killed a spouse and the mistress and her son killed his brother 'in a hunting accident'.
So, don't know how much happy happy joy joy I ever saw in the JW world, but I sure never saw anyone really come in because of FS unless you count the spiritual kidnapping that basically happened to my mom as an infant.ff
