The wife’s parents address where she lived may not have been important at that stage; it was not at a formal investigation yet... he got out before they could go after him about not supporting a wife and child.
Questions to all, for discussion purposes:
For what reason would INS be skeptical about whether Barack Obama was the father?
To what advantage would it be for BHO to admit having a wife and child in 1961?
because, if you read throught the file, you'll find that they were suspicious that the marriage was a fake.
