In all fairness, organizing old photos in general (especially scanned in pre-digital ones) is pretty much a horrid task in most cases. I'm dealing with it right now and stuff is linked to all over my hard drive, dupes in different formats at different levels of quality, limited metadata, etc. New stuff suffers from there being just so much of it--much of it repetitive--but at least it's in some semblance of order.
Afew years ago, I ran all my family photos through a script that renamed them based on the year, month, and date. I may have retained the old name in the metadata. I'm looking for the script I used. I also have some tools that compare hashes and find duplicates. You can google that stuff, or if you want to hire me to help, PM me.

I actually don't care about the filename, although maybe once things are cleaned up I'll do an export of everything. It's all in a Lightroom catalog now. It's "just" a matter of adding more primarily location-based metadata and making sure everything I especially care about is in appropriate Collections.
