If you are thinking of doing a JW funeral I would be aware that you can't trust these people. My brother and sister persuaded me to let a JW take my father's service at the crematorium saying that he and his wife were friends of my mother's from the KH and my dad often had chats with him because they lived close by.
Well I wrote down lots of memories about my father and they were handed to this guy for the service. On the day he turned every single thing I said into preaching about the cult. Every sentence, every memory, using my name each time he introduced a memory! My father was agnostic and believed in evolution. His sisters were horrified and thought it was all my fault. Just don't trust them to follow your wishes, they will make it into a preaching session. The end justifies the means with these people and they may well lie to you.
