Once they have a relative, it isn't that difficult to narrow it down to Bob. Think about it, you went from 350 million possible candidates to maybe 50 or less.
Go to the relative and ask them if they have any relatives in or near state X or city Y. That should narrow it down to a handful. And also you can narrow further by gender. Once you find a relative, you can logarithmically cull the search space.
