You really are in a rough time of your life. I've been through it and am out on the other side now. I lost my parents and my brother and I have no other siblings. I lived in northern Ohio, parents were in Florida, and brother was in Colorado. Everything landed in my lap, too, but what you are doing is so wonderful. What I know about you is that things will be done correctly, too. Lucky you, huh? LOL But, your family will appreciate it and you will be glad, once everything is over, that you have taken care of things properly. It gives you a good feeling knowing that you loved them so much and took care of them right to the end...and even more.
Oh, I love dixieland jazz, too. I bet the local library would be interested in those too. I'm not sure if they lone out records but I sure would ask about that. There might be some type of music library, too.
