How to Find Facebook Friends in Other Friends’ Lists
Facebook Timeline pages have Friends links you can find below the cover photo (unless the member has chosen to block the box from view).
If you have Facebook friends in common, you’ll see the number of mutual friends on the box.
By clicking the box, you can view all of a particular friend’s connections in a new window.
And you also see links to your Mutual Friends.
You can search through the list (looking for a specific person) in two ways: by typing the person’s name in the Search Friends box and clicking the magnifying glass, or by scrolling down the list and viewing each friend individually.
Another way to search is by typing a name into the text box next to the magnifying glass: As you type, names that match your search appear. When someone is not already your friend on Facebook, to the right of each entry is an Add Friend link that you can click to send a friend request.
