To my knowledge, none of the JWs she knew has come to visit her, although she had dozens of JWs in her home over the years. To be fair, a majority of the JWs she knew are no longer around now because she is 94 and most of them are dead, but there are a few younger JWs around who should remember her.
It's simple. In the past she gave her time, her assets, her hospitality, and even her love & friendship to them, but now -- she has nothing more to offer to them -- so she has simply been forgotten -- off their radar because their radar only alerts them to what they can GET from her.
