This is a very, very sad story. I cannot help but feel for the daughter.
The words of Jesus come to mind: 'By this all will know that you are my disciples-if you have love among yourselves' (John 13:35).
Shame on the 2 elders and the pioneer woman for failing to inform their sibling sister of the loss of her father! True Christian love dictates that they automatically would have.
Sad to say this is no isolated case. As others have mentioned this act of discourtesy is only too common among Jehovah's Witnesses.
This is why many in the world hope and pray that one day God damns the self-exalted Governing Body 8!
