But ... it's not about the money.
I'm feeling charitable about this one. Maybe it's about the other woman wanting her sons to know that their father was a hero. Maybe both of these women realize that all of the children will be better of with this larger family including more children.
And, the money's there. I'd rather see it go to the children (if the DNA tests confirm the claim) than to all the charities that have been grabbing it for other purposes than to support victim's survivors.
