I had .. umm... dealings involving a Canadian who owned a winery in the US, but tried to pretend he didn't for... reasons.

In about half an hours work I found copies of the county land tax record with his winery's acreage, tax assessment, and name of the corporation; found the state corporation record showing the transfer from the previous owner to his company, signed by him; and found the state alcohol tax authority licence showing the class of licence issued, location of winery, and name of his company with his name as the contact.

It's amazing what's online, publicly available for free. And then there's what's online and available for just a small fee.
