Have to admit, like the others, in all my years of recording and publishing online and in books only once have I met with an objection from a family of a recorded person and that was very understandable.
It was of a very young singer and he still had young brothers who might have come across his singing online. We of course respected the wishes of the family. Other than that family members are almost always delighted to know their relative was being honoured in this way.
Another way out is to publish and be damned, then if anyone objects you simply delete what they object to.
