Very true, and very interesting.
I fortunately come from a family of hoarders so I have in my possession a lot of files full of original documents and photos dating back to the mid-19th century; dozens of letters between relatives, prison papers (g-g-grandad was a transported convict), wills, legal docs, shipping papers, notes of all sorts. I do remember that some time ago the Fremantle (W.A.) library said they would be interested in photos and papers related to the history of the area.
None of my children is even vaguely interested in family history, though they are still relatively young and maybe as they get older they will take it up. I hope they do. My plan is to leave all my family history papers in files, backed up with pen drives, and hope that someone takes pleasure in them some day.
One thing I can't agree with more is the comment about labelling photos. I have so many photos, old and more recent, which I'm sorry to say I can't put names to. It's such a shame when you look at a photo and have to wonder who it is - and you have no way of finding out!
