I will never forget the feeling I was given as a child, that women were worthless, (not from my own parents) when our cleaning lady asked us to pray that her grandchild would be a boy, so that he could 'carry on the family name'. Which was something really everyday like say, Brown or Smith. I did pray for her as well!
Then my brother got a bit obsessed with 'carrying on the family name' , and really got quite angry when I gave it to my children, saying that I had 'no right' to do so.
so yes, it seems to be women as extensions, who are less important becuase they do not have their own name. OK the cleaning lady scenario was back in the 70s but it did affect me at that time, got me thinking a bit.
