I read a story a while back about a foster mom who ended up adopting six sisters. Her name is Lacey Dunkin and she was a single woman, not expecting her foster-parent application to be taken seriously, even though she wanted it very much. She was asked to take four sisters into foster care on an emergency basis, and a fifth girl (a newborn) was added shortly after. The birth mom took the girls back, but when another daughter was introduced to the family, the birth mom asked Lacey to take them all. Lacey formally adopted them in July of 2013.
