Terry's mother has 3 children.
16 year old boy S and 14 year old girl M who share a last name (A).
I believe these two are full siblings to each other.
Terry - 11 years old with a different last name.
I believe he is a half sibling to the other two.
I do not know about Mom's partner and her children.
I just know that those are the 3 children from Terry's mom.
I think the initial reporting of "stepbrother" was just an error. :twocents:
Thanks for clarifying. That sounds correct from what I have read. Maybe the "step" error occurred after interviews with Terry's father. He stated the half siblings were his stepchildren.
