How my various wallet.dat files got mixed up I do not know.
My guess is you made a backup, then another backup and another backup. That creates 3 different wallets, partially with the same addresses. If you ever changed the password of the wallet, new addresses in that wallet were not in your old backup.
ALL in all very good, I was able to recover some old stuff. Big thank you to community.
Congrats! Forgetting about your wallets for 7 years is a great way of HODLing
