Where to publish a story

Like johnny said above I think it would first depend on what type of music the relative was in. You could do a search online for the specific type 'country magizines', 'jazz mags', 'rythem and blues'. Once you found one or more that fit you could contact them. Also like johnny said you could publish with one of the online companies. I have published a lot of personal stories on Associated Content. These places don't normally pay a lot but it would give you exposure if you plan to write more. I think I'd go for the first idea though.
