Youve got that the wronmg way round. A man cant marry a halfsister, a woman cant marry a halfbrother. Adopted children can marry their adopted brother or sister.http://www.adviceguide.org.uk/index/your_family/family/getting_married.htm#Who_can_get_married
They are blood half brother and sister. But because of the law.They are not related.When a person is adopted they no longer belong to their blood relatives they are part of the family they were adopted into.So a non related adopted brother and sister can not marry.Yet a half brother and sister can.In this case. They share the same blood/birth mother.
My view is very simple..forget all the sites that state this and that.XX Jeannine
