I have "inherited" my mothers, grandmother's and great grandmother's albums. Yes, there are many people in photos (mostly non-relatives) that I can not identify, but I have gone thru all the photos (several hundred) and identified the ones I do know. Often times only identifying a person because I recognized them from a different photo. I then try to share these photos with anyone and everyone that wants them so they won't easily be lost (like in a house fire). I have seen some of the photos online, but since I don't know who originally had "rights" to it I am cautious on sharing them on wiki. I've always thought (probably erroneoulsy) that as long as I am not making money off the photo and give credit to the person that took it (if known) copyright laws don't come into play. After all, what good is a photograph if noone ever sees it ?
