简明释义：
If a person was married to the deceased spouse for at least 10 years and was divorced, the Survivor Benefit is available just the same as if the couple had not divorced (as long as he or she has not remarried prior to age 60, as mentioned above).
FORBES: The Social Security Survivor Benefit - Part 1
The couple had no children and Breuning never remarried.
他们一生都没有孩子，布莱宁也没有再婚。
It might be that one of the parents has died and the remaining parent has remarried and then that new husband and wife couple don't want the kids from the previous marriage.
有的也许是父母中有一个人已经过世，剩下的那个会再婚，而新找的丈夫或是老婆不想要对方和前任生的孩子，因此这些孩子就流落到河内街头了。
