Oh yes, and not just spouses. My grandfather was never a jw, never lived a religious life, but at the end, his daughter had a jw perform the service (not at the KH though). They are also known to crash funerals, like they did when my mother died, and we had the service held at a church (she had been inactive for years, and 4/5 of her children are non-jws, one dfed). A "brother" then crashed her funeral, to preach to us "fallen away"-kids. I could have, and should have, strangled him with my bare hands. They are evil people.
