That's awesome, thanks for sharing :) I have an idea for you since you have those pictures in a digital format. Try uploading all the collection to Google Photos. It will automatically recognize objects and faces. Then you can search the photo collection as you would do in google search. For example, you can search "food" then all the pictures with food in them will be sorted. Or you can search for "nature" and all pictures taken in nature will show and so on. Then if you have the dates, you can sort them by date and see some interesting patterns maybe. Google can also sort them according to faces with a bit of help from you since it has a hard time recognizing faces of people as they grow up.
