Pictures are very important to a complete family history. I've tried to get pictures of people, houses they lived in and even their graves. A tip a great aunt gave me when I was a teenager is still very true "Always record the names of the people in the pictures." Many of my grandmothers pictures had no names. Even she didn't remember who some were after she got older. I have tried to record the names of the ones my mother knows but she doesn't know many of them.
Don''t forget to record the names of people when you put pictures on the computer.
