At least you have photos of your love ones. I have just joined ancestry.com to learn about the family I don't know. I was raised in foster homes and a children home so I don't have family stories, photos, names or dates. i have made progress because of someone else's work, a 1st cousin 1x removed, I now know what some of my relatives look like. If i should take a photo of a relative from another tree it will only be so that I have a face to go with the name.
I do photography as a hobby so I understand the feeling regarding photos being taken because it's a great photo.
I used a photo and I received a message saying let's send a Thank You to the person.
