Does your son live with you? Has he ever bought anything online, using his email and your address? Probably linked that way.
I bought my step-daughter some baby shower stuff on Amazon, using my account and her shipping address. Some data miner decided she lives with me now, and I get mail for her at my house.
We also get mail for my wife's ex husband here. They've been divorced 13-14 years. Nothing bad, just catalogs from the tech college, cable tv signups. No credit card offers, I'm worried my wife would try to f him over and fill one out.
