Yes, my take from the articles that I have read is that there are mainly Sunnis in al-Mulmudhiya, some with the same last name, belonging to the same tribe although unrelated.
I believe that it is the Washington Post article where it is reported that the jounalist interviewed 2 men with the same name in al-Mulmudhiya, but the 2 were not related.
One has to also take into consideration the multitude of American newspaper writers that are interpreting this story in the safety of their own stateside office, etc., and not providing info gathered from a face to face interviews.
Remember Jayson Blair? Well combine the American Jayson Blairs and the writers of the Iraqi Resistance Reports and what is it that you get?
I highlighted the sentence about the girl seldom leaving home, because it is in direct conflict with another version that said she had to cross the checkpoint everyday.
I still have a hard time believing that 5 soldiers would conspire to do this, I really do.
