mmmm Missfoodlove , bit of a knee jerk reaction me thinks! Have you ever taken family snaps and caught strangers in same snap. Did you ask for their permission to take the photos or show them to family and friends?
It isn't all that different really. Strangers won't know who the heck they are anyway, unless people are 'tagged in' their name won't appear and if they ARE tagged in it means they are on Facebook themselves! It will appear on their timeline and they can delete if if they choose to. Unlikely the daughter will type out all the names of the people in the 'comments' but even then they will be overlooked by people who don't know them.
I agree with others this has nothing really to do with the photos......
Passports not in the drawer I always keep them in. Turning the place upside down.
