So for a jumping off point

Dead Bombers Wife
Richard W Russell
Warren K Russell

is the possible lineage.

You need at least one more to see if Richard W Russell became a Skull and Crossbones member due to lineage.

But even if she is not related to the founder of Skull and Crossbones..one member could be enough to gain her some protection.

For all we know, she could have been an FBI/CIA/etc plant to infiltrate Dead Bombers activities...

which may be why she is getting a pass.
