Research Ethics

Well, I think getting consent will be fairly easy for me (after all, it's my family).  And my research will not include any human experimentation, just asking questions, so that simplifies things quite a bit.  I think the hardest part is going to be getting my family to talk openly and truthfully.  And as far as I know, there won't be any risks involved (my grandpa might think otherwise).  I do wonder how the confidentiality aspect will come into play, if at all...
