Eighth Circuit -- Patti Beeler v. Michael J. Astrue

 Agency determination that four statutory methods are sole methods of establishing paternity/maternity entitled to deference under Chevron  and Auer.  

Prior agency ruling that children of valid marriage entitled to the benefit does not estop present ruling, as state intestacy laws establish that the designation doesn't apply to present case (posthumously conceived child)

Circuit split flagged.
