Street View allows you to navigate and 'travel' the neighbourhoods where your family lived their lives. It provides you with a much greater feel for specific locations or areas than random snapshots bring. Only problem .... you can lose hours on it!!
You can access Street View via http://earth.google.co.uk (which is free to download, and, in my opinion, the easier and faster option) or www.maps.google.com.
Have fun exploring!
