Sounds like a job for the "6 degrees of Kevin Bacon" database.
I actually have all my Grateful Dead and related Dead family stuff together, including the solo projects, side project bands, New Riders of the Purple Sage, Phil and Friends, etc.
I suspect a lot of us do this.
"Deadbase" does a great job with the GD family tree, As does the several volumes that make up "The Grateful Dead Taper's Compendium"
