The nine families live on the intersections shown.
There is no point including a lengthy solution with this puzzle as it can be solved in a number of different ways. As with other logic puzzles of this kind, a popular method is to write the names of all the families in each one of nine spaces representing the intersections then by applying the clues remove the families one by one until only a single family remains in each space.
