I agree. I don't think you should give up on talking to your family. At home around my family is literally the only place I really feel comfortable speaking. It sounds like you care about your family, and if they really care about you they'll be patient and listen. If you're talking about older family members, could you maybe write down questions you want to ask them? I have a really hard time talking to older people because they can never understand me. My grandparents aren't very old and my grandad on my dad's side is probably my closest friend in the world, but on my mom's side my great grandparents are practically impossible to communicate with. I don't even know if they really understand about my speech impediment and I get the same confused look you mention. So what I do instead is I write them letters occasionally and that works pretty well and they like it. In person I get other people to do the talking for me.
