Do you have pictures or other ephemera that you've not tried to save in some way? Don't wait until it is too late.
For pictures, make certain to include identification if you have it, who made the digital image, where they got it, and who made identification. Those pieces of information are good ones to have for someone who may come across your image years later.
Note: Christena Ufkes Habben is a sister to my great-great-grandfather, Johann Ufkes (1838-1924).
