I've noticed there are professional widows in JW Land also. When they find out about a widower in the Hall that has just located their or something they make there move. The one case in particular I know about (although there are many) is that this Brother called his family and said that there's a sister in the Hall that keeps hanging on to him trying to get his attention and it was really bothering him. About 3 or 4 months later he calls his grown kids and sister and says he's getting married.
When he died, and it wasn't a mysterious death it was a legit health problem, the wife didn't even attend the memorial at the Hall, made sure he had all his paperwork in order, which means she got the property and house he had instead of his adult children and they haven't heard from this faithful servant of Jah since their father's death.
