So turns out there's this concept called "Escheatment" where governments will take custody of unclaimed property, like if a check is sent to your previous address so you never cash it because you didn't know about it.
In the US, this is handled by state governments. If you google "[state] escheatment" you should see a .gov website that will let you search your name to see if they've got anything for you so you can file a claim. There are aggregator searches like missingmoney.com, but it didn't list some of the entries that the official one did so I wouldn't recommend it. You should check any state you've lived, and maybe your family too if you're feeling saucy.
I didn't find anything in my name, but it showed similar results by last name and I found stuff for my mom, dad, sister, a few aunts and uncles, and even my late grandmother! It usually won't be much, but it's your property, so you might as well get it, right? Plus in the case of your family you get to ring them up and say "Hey, how would you like some money?"
This is the least evil application of this, but I'm surprised a site backed by government data lets you search a name and get a historic address associated with that name.
in my state you can enter someone's first and last name into the voter registration database and get their home address and party affiliation....I learned this when I checked my registration status and discovered that there is someone else with the exact same name as me that lives less than a mile from me and is a registered republican
