My spouse's multiple AKAs

Would you not become suspicious and scare that your spouse [might] have been engaging in illegal activities [behind your back] had you stumbled across the multiple AKAs [also known as] along with three different dates of birth that he uses to identify himself to the authorities?  Why go through such effort unless one was / is involved in some kind of scam?

To whom did I marry and into what did I get myself into?
